Detailed Description
The embodiment of the application provides a domain name address resolution method, and solves the technical problem that in the prior art, a client is guided to a WEB server with redundancy and weak disaster recovery service capability by an IP address which is possibly returned to the client by a DNS (domain name server).
In order to solve the technical problems, the general idea of the embodiment of the application is as follows:
a method of domain name address resolution, the method comprising: receiving a domain name resolution request sent by a client; determining an IP address set corresponding to a target domain name contained in the domain name resolution request; monitoring the service state of a first IP address in the IP address set; if the first IP address cannot provide the access service, determining a second IP address capable of providing the access service from the IP address set; the first IP address is different from the second IP address; and returning the second IP address to the client so that the client can access the second IP address.
In this embodiment, after receiving a domain name resolution request sent by a client, an IP address set corresponding to a target domain name included in the domain name resolution request may be determined, a service state of a first IP address in the IP address set is monitored, if the first IP address cannot provide an access service, a second IP address capable of providing the access service is determined from the IP address set, and the second IP address is returned to the client, so that the client accesses the second IP address. It can be seen that, in this embodiment, service state monitoring is performed on a first IP address in an IP address set corresponding to a target domain name that a client wants to access, when the first IP address can provide access service, the first IP address is returned to the client for use, and if the first IP address cannot provide access service, a second IP address that can be accessed is determined again from the remaining IP addresses, and the second IP address is returned to the client for use, so that probability of successful access to a WEB service end and access efficiency of the client are improved, and user experience is also improved.
In order to better understand the technical solution, the technical solution will be described in detail with reference to the drawings and the specific embodiments.
First, it is stated that the term "and/or" appearing herein is merely one type of associative relationship that describes an associated object, meaning that three types of relationships may exist, e.g., a and/or B may mean: a exists alone, A and B exist simultaneously, and B exists alone. In addition, the character "/" herein generally indicates that the former and latter related objects are in an "or" relationship.
The present embodiment provides a domain name address resolution method as shown in fig. 1, which includes steps S11 to S15.
Step S11, receiving a domain name resolution request sent by a client; the client domain name resolution request supports double stacks, namely IPv4/IPv6 request and resolution service;
step S12, determining an IP address set corresponding to a target domain name contained in the domain name resolution request;
step S13, monitoring the service state of the first IP address in the IP address set;
step S14, if the first IP address can not provide the access service, determining a second IP address which can provide the access service from the IP address set; the first IP address is different from the second IP address;
and step S15, returning the second IP address to the client so that the client can access the second IP address.
The method provided by the embodiment can be applied to a DNS server, an authoritative DNS and a cache DNS.
In step S11, a domain name resolution request sent by the client is received. The client domain name resolution request supports dual stacks, namely IPv4/IPv6 request and resolution service;
the client sends a domain name resolution request to the DNS, wherein the domain name resolution request comprises a target domain name.
Regarding step S12, the IP address set corresponding to the target domain name included in the domain name resolution request is determined.
After receiving the domain name resolution request, the DNS server acquires a target domain name from the domain name resolution request. And according to the target domain name, determining an IP address set corresponding to the target domain name from a comparison table of the domain name and the IP address. Typically, a target domain name may correspond to one or more IP addresses, and different IP addresses may be served by different servers.
With respect to step S13, service status monitoring is performed on a first IP address in the set of IP addresses.
In the related art, the DNS servers can be divided into an authoritative DNS and a forwarding DNS, where the authoritative DNS refers to a server that has the right to modify the relationship between the domain name and the IP address, and the forwarding DNS can only forward the relationship between the domain name and the IP address, but not modify it.
In addition, the DNS can inquire local authoritative domain name resource records and cache resource records according to a domain name resolution request of the client, if the local authoritative domain name resource records and the cache resource records are hit, the local authoritative domain name resource records and the cache resource records are directly fed back to the client, if the local authoritative domain name resource records and the cache resource records are not hit, the domain name resolution request is forwarded to an upstream DNS, and when the feedback resource records are obtained from the upstream DNS, the local authoritative domain name resource records and the cache resource records are fed back to the client.
It can be seen that, the DNS server in the related art can only resolve or forward the relationship between the domain name and the IP address, and does not identify and determine the validity of the domain name resource, and if the WEB server corresponding to the IP address fails, the DNS server does not know that the WEB server has failed, and then still sends the corresponding IP address to the client, so that the client cannot successfully access the corresponding WEB server.
In order to solve the problem, in this embodiment, a first IP address is determined from the IP address set, and a service state of the first IP address is monitored, and when the first IP address can provide access service normally, the DNS server returns the first IP address to the client, so that the client can access the WEB service. When the first IP address cannot normally provide the access service, step S14 is performed.
The first IP address may be an IP address with a highest preset weight in the IP address set. In general, the authoritative DNS may set the preset weight, and the preset weight of each IP address may be set according to an actual situation, which is not limited in this embodiment. The IP address with the highest preset weight in the IP address set can be determined according to the number of clients accessed in real time. That is, the IP address with the highest preset weight in the IP address set can be adjusted according to the number of clients accessing in real time, so as to provide a relatively stable IP address for the client when the next client accesses. For example, the IP address set includes 3 IP addresses, which are 1.1.1.1,2.2.2.2,3.3.3.3, and the corresponding preset weight is 4. Then the IP address with the highest preset weight is 1.1.1.1, which can be used as the first IP address. When the number of client accesses of 1.1.1.1,2.2.2.2,3.3.3.3 is 100. At this time, when the next client accesses, 2.2.2.2 may be taken as the first IP address.
Of course, the first IP address may also be determined as follows: and sorting the historical access records of all the IP addresses in the IP address set, and determining the successful access probability of all the IP addresses, wherein the first IP address can be the IP address with the highest successful access probability in all the IP addresses.
In addition, the service status monitoring is performed on the first IP address in the IP address set in the following three ways.
And (mode 1) monitoring the service state of the first IP address by adopting an Internet packet searching device.
And (mode 2) monitoring the service state of the first IP address by adopting a hypertext transfer protocol.
And (mode 3) monitoring the service state of the first IP address by adopting a hypertext transfer security protocol.
An Internet Packet explorer, namely ping (Packet Internet Groper), is a program that can be used to test the network connection amount, and mainly judges whether the network is unblocked based on the network layer.
The hypertext Transfer Protocol (HTTP) is a simple request-response Protocol, which generally operates in an application layer and can be used to implement information transmission between a client and a server.
The hypertext Transfer Protocol over secure HTTP Layer is an HTTP channel targeted for security, and the security of a transmission process is ensured through transmission encryption and identity authentication on the basis of HTTP. HTTPS typically runs at the application layer and may be used to enable information transfer between a client and a server.
The service state is monitored through ping, whether a network layer between the client and the server is unblocked can be determined, and when the network layer between the client and the server is unblocked, the application layer between the client and the server cannot be guaranteed to be unblocked. Monitoring the service state through the HTTP or HTTPs can determine whether the application layer between the client and the server is clear, and if the application layer is clear, it means that the network layer is necessarily clear.
Therefore, under a better condition, the service state of the first IP address can be monitored by adopting a hypertext transfer protocol or a hypertext transfer security protocol, and the accuracy of monitoring the service state of the first IP address can be improved.
With respect to step S14, if the first IP address cannot provide the access service, determining a second IP address capable of providing the access service from the IP address set; the first IP address is different from the second IP address.
When it is determined that the first IP address cannot provide access service, meaning that the client cannot successfully access the corresponding WEB service even if the first IP address is returned to the client, the first IP address may be removed from the IP address set at this time, so as to obtain an updated IP address set; and re-determining the preset weight corresponding to each IP address in the updated IP address set.
For example, the IP address set includes 3 IP addresses, which are 1.1.1.1,2.2.2.2,3.3.3.3, and the corresponding preset weight is 4. Then the IP address with the highest preset weight is 1.1.1.1, which can be used as the first IP address. When the first IP address, i.e. 1.1.1.1, cannot provide the access service, the first IP address is removed, the updated IP address set includes 2 IP addresses 2.2.2.2,3.3.3.3, respectively, and the updated preset weight is 2:1 (obtained according to 4:2).
And according to the sequence of the preset weights of other IP addresses except the first IP address in the IP address set from high to low, sequentially monitoring the service state of each IP address until a certain IP address can provide access service, and taking the certain IP address capable of providing the access service as the second IP address.
The other IP addresses in the set of IP addresses except the first IP address may constitute an updated set of IP addresses. And determining the preset weight of each IP address according to the updated IP address set, sequencing the IP addresses from high to low, sequentially monitoring the service state of each IP address until the IP address capable of providing the access service appears, and recording the IP address capable of providing the access service as a second IP address.
For example, the updated IP address set includes 2 IP addresses, which are 2.2.2.2,3.3.3.3 respectively, the updated preset weight is 2:1, the service status of 2.2.2.2 is monitored first, and if 2.2.2.2 can provide access service normally, 2.2.2.2 is used as the second IP address. If 2.2.2.2 can not provide access service normally, the service status monitoring is continued to be carried out on 3.3.3.3, and if 3.3.3.3 can provide access service normally, 3.3.3 is taken as the second IP address. And if 3.3.3.3 cannot provide the access service normally, feeding back characters such as WEB service end faults and the like to the client so as to remind a user of the client that the user cannot access the target domain name normally.
Regarding step S15, the second IP address is returned to the client for the client to access the second IP address.
And after the second IP address is determined, the second IP address corresponding to the target domain name can be returned to the client, so that the client can access the WEB server of the second IP address.
It should be noted that the method provided by the present embodiment can be applied to a DNS server. The DNS server may be an authoritative DNS and a forwarding DNS, and when applied to the authoritative DNS server, may be executed according to the above steps S11 to S15. When the method is applied to the forwarding DNS server, the forwarding DNS server can obtain the IP address set from the authoritative DNS server, and then the steps S11 to S15 are performed, and the IP address which can finally provide the access service is returned to the client.
To sum up, after receiving the domain name resolution request sent by the client, the embodiment may determine an IP address set corresponding to a target domain name included in the domain name resolution request, perform service state monitoring on a first IP address in the IP address set, determine, if the first IP address cannot provide access service, a second IP address capable of providing the access service from the IP address set, and return the second IP address to the client, so that the client accesses the second IP address. It can be seen that, in this embodiment, service state monitoring is performed on a first IP address in an IP address set corresponding to a target domain name that a client wants to access, when the first IP address can provide access service, the first IP address is returned to the client for use, and if the first IP address cannot provide access service, a second IP address that can be accessed is determined again from the remaining IP addresses and is returned to the client for use, so that the probability and the access efficiency of the client that successfully accesses a WEB service end are improved, and user experience is also improved.
