Description

IP address processing method, system, device and electronic equipment

Technical Field

The present invention relates to the field of internet technologies, and in particular, to a method, a system, a device, and an electronic device for processing an IP address.

Background

A Domain Name System (DNS) is a set of systems that maps Domain names to Internet Protocol (IP) addresses, and enables users to access the Internet more conveniently without having to remember IP strings that can be read directly by a machine. The DNS system is almost the basis of all current network services, and for a service with many users, the DNS system generally performs load balancing operation, that is, configures a series of different IP addresses for users in different areas, where each IP address corresponds to a network server.

Generally, an authoritative server in a DNS system will configure a different series of IP addresses for central servers in different regions. Taking the user of the link in beijing as an example, if the user accesses the IP of the link in beijing to the domain name www.iqiyi.com, the result shown in fig. 1 is obtained: the DNS authoritative server configures 6 IP addresses for the service of the domain name www.iqiyi.com aiming at the central control servers in different areas, and users in different areas of Beijing Unicom can access www.iqiyi.com through the different IP addresses corresponding to the areas. When a certain IP address is unavailable in fig. 1, the DNS authoritative server cannot sense the unavailable IP address, and still resolves the domain name. In the prior art, a server of an internet data center is generally adopted to detect a fault and feed back the fault through a service line.

However, the inventor finds that the prior art has at least the following problems in the process of implementing the invention:

in the prior art, when a server of an internet data center is used for fault detection, usually a detected fault is fed back through a service line, but the feedback delay exists in the processing mode, so that a user side cannot timely sense an unavailable IP address, and the user side can continue to use the unavailable IP address, which results in that the user cannot successfully access a domain name corresponding to the IP address.

According to the invention, the detection equipment is introduced into the DNS system to access each IP address in the first area, the access result is sent to the central control server, the central control server judges whether each IP address in the network service is available or not, and sends the information whether each IP address is available or not to the DNS authoritative server, and the DNS authoritative server timely takes off the unavailable IP address, so that the availability of the network service is ensured.

The technical solutions in the embodiments of the present invention will be described below with reference to the drawings in the embodiments of the present invention.

An embodiment of the present invention provides an IP address processing method, and fig. 2 is a flowchart of the IP address processing method provided in the embodiment of the present invention, including the following steps:

step 201, at least one probe device in a first area sends a network service query request to a DNS authoritative server.

The method provided by the embodiment of the invention can be applied to a Domain Name System (DNS). The DNS system typically configures users in different areas with a different series of IP addresses, where each IP address corresponds to a network server.

In order to enable a user to timely sense unavailable IP addresses, at least one detection device is preset in the first area and used for accessing all IP addresses in network services in the first area. The preset detection equipment needs to meet the following conditions respectively: when the system works in a networking state for a long time, each detection device can send a network service query request to a DNS authoritative server and access each IP address in the network service in the first area, but the time for a user to use the detection device for detection is short; the resource consumption is low, and all the detection equipment can work for a long time at the same time when a large number of detection equipment exist at the same time; the efficiency of sending messages and accessing IP addresses is high, the running speed is high, the information processing capacity is strong, and the normal use of hardware where equipment is located cannot be influenced when detection activities are carried out; the edge network environment where the detection equipment is located is stable; the user population using the detection device has wider geographical distribution; the detection device meeting the above conditions can be usually installed in electronic devices such as a home router, an internet set-top box, an intelligent home, a television set, and the like.

Before the detection device works, a business agreement can be achieved with a user in a network area where the detection device can access through a business means, and when whether each IP address is available or not is determined, enough detection devices are arranged in the first area according to the content in the business agreement so as to ensure the accuracy of the access result of the detection device.

At least one probe device in the first area sends a network service query request to a DNS authoritative server so as to query the DNS authoritative server for the IP address list in the first area. The network service inquiry request comprises request information of an IP address list in a first area which the detection device wants to inquire.

Step 202, the DNS authoritative server receives the network service query request sent by each probe device, and sends the IP address list of the first area to each probe device.

After receiving the network service query request sent by each probe device, the DNS authoritative server may send an IP address list in the first area to which the probe device requests access, which is included in the network service query request, to each probe device, so that each probe device in the first area may access each IP address in the IP address list. The IP address list in the first area may include a plurality of IP addresses, as shown in fig. 1, wherein 111.206.13.62, 111.206.13.63, 111.206.13.64, 111.206.13.65, 111.206.13.66, 111.206.13.61 are IP address lists in one area.

Step 203, each detection device receives the IP address list of the first area, accesses each IP address in the IP address list, and sends the access result of each IP address to the central control server.

Each detection device in the first area receives an IP address list of the first area sent by the DNS authoritative server, and accesses each IP address in the IP address list to obtain a corresponding access result, wherein the access result comprises two types: access success and access failure. When the detection device detects the network service corresponding to the IP address, the success of the access is displayed, and when the detection device cannot detect the network service corresponding to the IP address, the failure of the access is displayed. Each detection device can access each IP address in the IP address list respectively and send the access result of each IP address to the central control server.

And step 204, the central control server receives the access result of each IP address sent by each detection device, determines whether each IP address is available according to the access result of each IP address, and sends the information whether each IP address is available to the DNS authoritative server.

After receiving the access result of successful access or failed access of each IP address sent by each detection device, the central control server may determine whether each IP address is available according to the access result of each IP address. For example, for each IP address, the ratio of access success to access failure in the access results sent by all the probe devices is calculated, and if the ratio of access success is greater than the ratio of access failure, it may be determined that the IP address is available.

After the central control server determines whether each IP address is available, the central control server can send the information whether each IP address is available to the DNS authoritative server, and aiming at each IP address, the information whether each IP address is available is sent to the DNS authoritative server. The central control server may also send information on whether each IP address is available to the DNS configuration management server, and the DNS configuration management server may feed back information on whether each IP address is available to the DNS authority server.

In step 205, the DNS authoritative server receives information whether each IP address is available, and drops the unavailable IP address.

And the DNS authoritative server receives the information whether each IP address sent by the central control server is available, controls the unavailable IP address to be offline according to the information whether each IP address is available, and does not perform any processing on the available IP address.

The IP address processing method provided by the embodiment of the invention is applied to a DNS system, and the DNS system is introduced with at least one detection device to respectively access each IP address in the network service in the first area and send the access result to a central control server, the central control server judges whether each IP address in the network service is available or not and sends the information whether each IP address is available or not to a DNS authoritative server, and the DNS authoritative server takes the unavailable IP address off the line, thereby ensuring the availability of the network service.

With reference to the foregoing embodiment, in another embodiment provided by the present invention, step S201 may specifically include: at least one probe device in the first area periodically sends a network service inquiry request to a DNS authoritative server.

In order to detect and feed back the availability of the IP address in real time, at least one detecting device in the first area may send a network service query request to the DNS authority server at intervals of time, requesting to query the IP address list of the network service in the first area. The method for periodically sending the network service query request to the DNS authoritative server so as to continuously detect whether the IP address is available can feed back the availability of the IP address in the current network service in time and timely take off the unavailable IP address, thereby being beneficial to ensuring the availability of the network service.

With reference to the foregoing embodiment, in another embodiment provided by the present invention, the method for at least one probe device in the first area in step S203 to access each IP address in the IP address list respectively may specifically be: and respectively accessing each IP address in the IP address list through a preset service access format. Each detection device in the first area respectively accesses each IP address in the IP address list according to a preset service access format, where the preset service access format may be determined according to an accessed network service, for example, when accessing an FTP (File Transfer Protocol) server, the address format of the FTP is ftp.bbc.com; when accessing an HTTP (HyperText Transfer Protocol) server, the address format of HTTP is www.cnblogs.com/sublian/p/5460378. html, so the preset service access format is determined according to the web server being accessed. The access speed can be improved by accessing each IP address in the IP address list by adopting the preset access format, so that the detection equipment can effectively access each IP address.

With reference to the foregoing embodiment, in another embodiment provided by the present invention, in step S204, as a specific embodiment of the present invention, the method for determining whether each IP address is available according to the access result of each IP address may specifically include: the central control server counts a first number of inaccessible results in the access results of the IP addresses sent by each detection device aiming at each IP address; and when the first number corresponding to any IP address is larger than a first preset threshold value, determining that the IP address is unavailable.

When each detection device accesses each IP address in the IP address list, the access result includes two types: and when the detection device cannot detect the network service corresponding to the IP address, the access failure is displayed. Counting the number of results which are inaccessible when the IP address fails to be accessed in the access results of the IP address sent by each detection device as a first number for each IP address; when the first number is greater than a first preset threshold, then the IP address is determined to be unavailable.

The first preset threshold value may be arbitrarily set according to the total number of the detection devices and actual needs. For example, when there are 100 detecting devices, the first preset threshold is set to 80, that is, when there are 100 detecting devices, if there are more than 80 detecting devices feeding back that the IP address is not available, it is determined that the IP address is not available. The method provided by the embodiment of the invention determines that the IP address is unavailable simply and effectively by setting the first preset threshold when the number of results that the IP address is inaccessible is greater than the first preset threshold, and can determine whether each IP address is available through simple number statistics.

As another specific embodiment of the present invention, in combination with the above embodiments, fig. 3 provides a flowchart of a method after counting, for each IP address, a first number of inaccessible results in the access results of the IP address sent by each probe device in the above steps, and includes the following steps:

step 301, when the first number corresponding to any IP address is smaller than a first preset threshold and larger than a second preset threshold, the central control server sends an access instruction to at least one detection device in the second area.

Counting the number of results which are inaccessible when the IP address fails to be accessed in the access results of the IP address sent by each detection device as a first number for each IP address; when the first number corresponding to any IP address is smaller than a first preset threshold and larger than a second preset threshold, where both the first preset threshold and the second preset threshold are arbitrarily set according to the total number of the detection devices and actual needs, for example, when there are 100 detection devices, the first preset threshold is set to be 80, and the second preset threshold is set to be 50, that is, when there are 100 detection devices, if there are more than 50 detection devices and less than 80 detection devices that feed back that the IP address is unavailable, then, in order to determine the availability of the IP address, the IP address may be accessed again. Specifically, the central control server may issue an access instruction to the at least one probe device in the second area, so that the at least one probe device in the second area accesses the IP address, and does not continue to use the IP address in the first area, which may make the access result more accurate.

Step 302, at least one probe device in the second area receives an access instruction sent by the central control server, and sends a network service query request to the DNS authoritative server.

After receiving the access instruction sent by the central control server, at least one detection device in the second area requests to access the IP address list of the network service in the first area, and sends a network service query request to the DNS authoritative server.

Step 303, the DNS authoritative server receives the network service query request sent by each probe in the second area, and sends the IP address list of the first area to each probe in the second area.

After receiving the network service query request sent by each detection device, the DNS authoritative server sends an IP address list in a first region, which is included in the network service query request and is requested to be accessed by the detection device, to each detection device, so that each detection device in a second region can access each IP address in the IP address list.

And step 304, each detection device in the second area receives the IP address list of the first area, accesses each IP address in the IP address list, and sends the access result of each IP address to the central control server.

After each detection device in the second area receives the IP address list of the first area sent by the DNS authoritative server, each detection device accesses each IP address in the IP address list respectively, and the access result comprises two types: the method comprises the following steps that access success and access failure are displayed, when the detection equipment detects the network service corresponding to the IP address, the access success is displayed, and when the detection equipment cannot detect the network service corresponding to the IP address, the access failure is displayed; each detection device can access each IP address in the IP address list respectively and send the access result of each IP address to the central control server.

Step 305, the central control server receives the access result of each IP address sent by each probe device in the second area, and determines whether each IP address is available according to the access result of each IP address sent by each probe device in the second area.

After receiving the access result of successful access or failed access of each IP address sent by each detection device, the central control server may determine whether each IP address is available according to the access result of each IP address. For example, for each IP address, calculating the ratio of access success to access failure in the access results sent by all the detection devices, and if the ratio of access success is greater than the ratio of access failure, then the IP address is indeed available; or counting the number of successful access of the detection devices for each detection device, and determining that the IP address is available when more than half of the detection devices display successful access.

After the central control server determines whether each IP address is available, the information about whether each IP address is available is sent to the DNS authoritative server, and the information about whether each IP address is available is sent to the DNS authoritative server aiming at each IP address.

In the embodiment of the present invention, when the first number corresponding to any IP address is smaller than the first preset threshold and larger than the second preset threshold, in order to obtain accurate information on whether the IP address is available, each detection device in the second area may continue to access each IP address in the IP address list in the first area, so as to improve accuracy of an access result.

A specific method for determining whether each IP address is available according to an access result of each IP address sent by each probe device in the second area includes: counting a second number of inaccessible results in the access results of the IP addresses sent by the detection devices in the second area aiming at each IP address; and when the second quantity corresponding to any IP address is larger than a third preset threshold value, determining that the IP address is unavailable.

Counting a second number of inaccessible results in the access results of the IP addresses sent by the detection devices in the second area aiming at each IP address; and when the second number is larger than a third preset threshold value, determining that the IP address is unavailable. The third preset threshold may be arbitrarily set according to the total number of the detection devices and actual needs, for example, when there are 100 detection devices, the third preset threshold is set to 70, that is, when there are 100 detection devices, if there are more than 70 detection devices that feed back the IP address, it is determined that the IP address is unavailable. The method provided by the embodiment of the invention determines that the IP address is unavailable simply and effectively by setting the third preset threshold when the number of results that the IP address is inaccessible is greater than the third preset threshold, and can determine whether each IP address is available through simple number statistics.

An embodiment of the present invention provides an IP address processing method, which is applied to a detection device in a first area, and fig. 4 is a flowchart of the IP address processing method provided in the embodiment of the present invention, and includes the following steps:

step 401, sending a network service query request to a Domain Name System (DNS) authoritative server; and the DNS authoritative server receives the network service inquiry request sent by each detection device and sends the IP address list of the first area to each detection device.

At least one detection device in a first area sends a network service query request to a DNS authoritative server, and then queries an IP address list in the first area from the DNS authoritative server, and the DNS authoritative server receives the network service query request sent by each detection device and sends the IP address list of the first area to each detection device.

Step 402, receiving an IP address list of the first area sent by the DNS authoritative server, and accessing each IP address in the IP address list of the first area respectively.

After receiving a network service query request sent by each detection device, the DNS authoritative server sends an IP address list in a first area which is requested to be accessed by the detection device and is included in the network service query request to each detection device, and each detection device in the first area receives the IP address list of the first area.

Each detection device respectively accesses each IP address in the IP address list, and the access result comprises two types: the method comprises the following steps that access success and access failure are displayed, when the detection equipment detects the network service corresponding to the IP address, the access success is displayed, and when the detection equipment cannot detect the network service corresponding to the IP address, the access failure is displayed; each probing device will access each IP address in the list of IP addresses separately.

Step 403, sending the access result of each IP address to the central control server, so that the central control server receives the access result of each IP address sent by each detection device, determines whether each IP address is available according to the access result of each IP address, sends information whether each IP address is available to the DNS authoritative server, and takes the unavailable IP address off line through the DNS authoritative server.

Each detection device can access each IP address in the IP address list respectively and send the access result of each IP address to the central control server. And the central control server receives the access result of successful access or failed access of each IP address sent by each detection device and determines whether each IP address is available according to the access result of each IP address. For example, for each IP address, each probe device sends all the access results of each IP address to the central control server, and when there are 10 probe devices and 6 IP addresses, then 10 probe devices send the access results of 6 IP addresses to the central control server, and a total of 60 access results are generated. And the central control server calculates the ratio of successful access to failed access in the access results sent by all the detection devices, and if the ratio of successful access is greater than the ratio of failed access, the IP address is available. After the central control server determines whether each IP address is available, the information about whether each IP address is available is sent to the DNS authoritative server, and the information about whether each IP address is available is sent to the DNS authoritative server aiming at each IP address.

The IP address processing method provided by the embodiment of the invention is applied to the detection equipment in the first area, and the at least one detection equipment is introduced into the DNS system to respectively access each IP address in the network service in the first area and send the access result to the central control server, the central control server judges whether each IP address in the network service is available or not and sends the information whether each IP address is available or not to the DNS authority server, and the DNS authority server takes the unavailable IP address off the line, thereby ensuring the availability of the network service.

A specific probe device in a first area sends a network service query request to a DNS authoritative server, and the method comprises the following steps: and periodically sending a network service inquiry request to the DNS authoritative server. At least one probe device in the first area periodically sends a network service inquiry request to a DNS authoritative server. In order to detect and feed back the availability of the IP address in real time, at least one detection device in a first area sends a network service query request to a DNS authoritative server at intervals of time to request to query an IP address list of the network service in the first area, and the method periodically sends the network service query request to the DNS authoritative server so as to continuously detect whether the IP address is available, can feed back the availability of the IP address in the current network service in time, and timely takes the unavailable IP address off line, thereby being beneficial to ensuring the availability of the network service.

A specific method for a probe device in a first area to access an IP address in the first area included in network service information includes: and respectively accessing the IP addresses in the first area through a preset service access format. And each detection device in the first area respectively accesses each IP address in the IP address list according to a preset service access format, wherein the preset service access format can be determined according to the accessed network service.

An embodiment of the present invention further provides an IP address processing method, which is applied to a central control server, and fig. 5 is a flowchart of the IP address processing method provided in the embodiment of the present invention, and the method includes the following steps:

step 501, receiving an access result of each IP address in the first area, which is sent by at least one probe device in the first area.

The central control server receives an access result of each IP address in the first area, which is sent by at least one detection device in the first area, wherein the access result is obtained by the steps that the at least one detection device in the first area requests the central control server to inquire network services in the first area, the DNS authoritative server receives the network service inquiry request sent by each detection device after sending the network service inquiry request to the DNS authoritative server, and after sending the IP address list of the first area to each detection device, each detection device receives the IP address list of the first area and respectively accesses each IP address in the IP address list; the access result comprises successful access and failed access, when the detection equipment detects the network service corresponding to the IP address, the successful access is displayed, and when the detection equipment cannot detect the network service corresponding to the IP address, the failed access is displayed; each probing device will access each IP address in the list of IP addresses separately.

Step 502, according to the access result of each IP address, determining whether each IP address is available, and sending the information whether each IP address is available to the DNS authoritative server, so that the DNS authoritative server receives the information whether each IP address is available, and downloads the unavailable IP address.

And after receiving the access result of successful access or failed access of each IP address sent by each detection device, the central control server determines whether each IP address is available according to the access result of each IP address. For example, for each IP address, the ratio of access success to access failure in the access results sent by all the probe devices is calculated, and if the ratio of access success is greater than the ratio of access failure, the IP address is indeed available.

The IP address processing method provided by the embodiment of the invention is applied to the central control server, and can realize that the user can sense the unavailable IP address in time, and the unavailable IP address is downloaded, thereby ensuring the availability of network service. By introducing at least one detection device into the DNS system to respectively access each IP address in the network service in the first area and sending the access result to the central control server, the central control server judges whether each IP address in the network service is available and sends the information whether each IP address is available to the DNS authoritative server, and the DNS authoritative server takes the unavailable IP address off the line, the availability of the network service is guaranteed.

A specific method for determining whether each IP address is available according to an access result of each IP address includes: counting a first number of inaccessible results in the access results of the IP addresses sent by each detection device aiming at each IP address; and when the first number corresponding to any IP address is larger than a first preset threshold value, determining that the IP address is unavailable. When each detection device accesses each IP address in the IP address list, the access result includes two types: and when the detection device cannot detect the network service corresponding to the IP address, the access failure is displayed. Counting the number of results which are inaccessible when the IP address fails to be accessed in the access results of the IP address sent by each detection device as a first number for each IP address; when the first number is greater than a first preset threshold, then the IP address is determined to be unavailable. The first preset threshold is arbitrarily set according to the total number of the detecting devices and actual needs, for example, when there are 100 detecting devices, the first preset threshold is set to 80.

Specifically, for each IP address, the method after counting the first number of inaccessible results in the access results of the IP address sent by each probe device further includes: when the first quantity corresponding to any IP address is smaller than a first preset threshold and larger than a second preset threshold, an access instruction is sent to at least one detection device in the second area, so that each detection device in the second area receives the access instruction sent by the central control server and sends a network service query request to the DNS authoritative server, the DNS authoritative server receives the network service query request sent by each detection device in the second area and sends an IP address list of the first area to each detection device in the second area, each detection device in the second area receives the IP address list of the first area, and after accessing each IP address in the IP address list respectively, the access result of each IP address is sent to the central control server.

Wherein the second preset threshold is smaller than the first preset threshold; and receiving the access result of each IP address sent by each detection device in the second area, and determining whether each IP address is available according to the access result of each IP address and the access result of each IP address sent by each detection device in the second area. After counting the first number of inaccessible results in the access results of the IP addresses sent by each detection device by the central control server, if the first number corresponding to any IP address is smaller than a first preset threshold and larger than a second preset threshold, wherein the second preset threshold is smaller than the first preset threshold, and the first preset threshold and the second preset threshold are arbitrarily set according to the total number of the detection devices and actual needs; and the central control server sends an access instruction to at least one detection device in the second area, so that the at least one detection device in the second area accesses each IP address in the network service in the first area, and sends an access result to the central control server.

And after receiving the access result of each IP address sent by each detection device in the second area, the central control server determines whether each IP address is available according to the access result of each IP address and the access result of each IP address sent by each detection device in the second area. For example, for each IP address, calculating the ratio of access success to access failure in the access results sent by all the detection devices, and if the ratio of access success is greater than the ratio of access failure, then the IP address is indeed available; or counting the number of successful access of the detection devices for each detection device, and determining that the IP address is available when more than half of the detection devices display successful access.

Specifically, determining whether each IP address is available according to the access result of each IP address sent by each probe device in the second area includes: counting a second number of inaccessible results in the access results of the IP addresses sent by the detection devices in the second area aiming at each IP address; and when the second quantity corresponding to any IP address is larger than a third preset threshold value, determining that the IP address is unavailable.
