Technical Field

The present application relates to the field of communications technologies, and in particular, to a domain name system DNS processing method and apparatus, a storage medium, and an electronic device.

Background

The DNS (Domain Name System) is a distributed database on the Internet as a mapping between a Domain Name and an IP address, and a process of mapping a Domain Name to an IP address is called "Domain Name resolution". The domain name resolution needs to be completed by a special domain name resolution server, and the DNS is a server for domain name resolution. When a user inputs a DNS domain name in an application, the DNS server can resolve the domain name into an IP address corresponding to the domain name, and the user can finally surf the internet only through the IP address pointed by the domain name.

However, in the related art, DNS resolution is inefficient. For example, in a Wireless Fidelity (Wi-Fi) network, because a DNS server of the Wi-Fi network is configured incorrectly or stops working, DNS query of the Wi-Fi network fails, and normal internet access through the Wi-Fi network is not possible.

Detailed Description

The following description is based on illustrated embodiments of the application and should not be taken as limiting the application with respect to other embodiments that are not detailed herein. The term "module" as used herein may be considered a software object executing on the computing system. The various modules, engines, and services herein may be considered as objects of implementation on the computing system.

An execution main body of the domain name system DNS processing method may be the domain name system DNS processing apparatus provided in the embodiment of the present application, or an electronic device integrated with the domain name system DNS processing apparatus, where the domain name system DNS processing apparatus may be implemented in a hardware or software manner. The electronic device may be a smart phone, a tablet computer, a Personal Digital Assistant (PDA), or the like.

The following is a detailed description of the analysis.

An embodiment of the present application provides a domain name system DNS processing method, as shown in fig. 1, fig. 1 is a schematic flow diagram of the domain name system DNS processing method provided in the embodiment of the present application, and the domain name system DNS processing method may include the following steps:

101. when a DNS query request aiming at a target domain name is detected in a state that electronic equipment is accessed to a wireless network, first success power of DNS query through the wireless network is obtained, wherein the first success power is obtained based on information about success or failure of DNS query through the wireless network in a historical time period.

The Domain Name (Domain Name), abbreviated as Domain Name or network Domain, is a Name of a computer or a group of computers on the internet, which is composed of a string of names separated by points, and is used for identifying the electronic position or geographical location of the computer during data transmission. For example, the domain name may be www.1234567.com.cn. The DNS is a distributed database on the world wide web as a mapping between a domain name and an IP address, which enables a user to access the internet more conveniently, and is a server for converting the domain name and the IP address corresponding to the domain name. The DNS stores a table of domain names and IP addresses corresponding thereto to resolve the domain name of the message. The process of finally obtaining the IP address corresponding to the domain name through the domain name is called domain name resolution (or host name resolution).

Specifically, the DNS query request may be a query instruction initiated by an application installed in the electronic device to a corresponding DNS server for a target domain name, so as to obtain a DNS resolution result including an IP address of the target domain name.

In the embodiment of the application, the first success rate can be obtained based on the information about whether the DNS query is successful or not through a wireless network (e.g., a Wi-Fi network) within the historical time period. For example, taking an example that a system installed in the electronic device is an android system, the android system itself has a module for counting a DNS query success rate. Specifically, the module may be a module specially used for sending a DNS message, and if a DNS response message is not received within 5s, the DNS query is considered to be failed at this time, and if 10 consecutive DNS messages within a preset time have no response, the success rate of the DNS query is considered to be 0, so that it is determined that the DNS server has a problem and cannot normally resolve the DNS.

102. And if the first power does not reach the preset threshold value, sending a DNS query request to a corresponding DNS server through the accessed data network.

It should be noted that the preset threshold may be set by a person skilled in the art or a product manufacturer according to actual requirements, for example, the preset threshold may be 0%, 5%, 10%, etc., and this is not specifically limited in this application.

In a specific implementation process, when the first success rate does not reach the preset threshold, the data network may be pulled up (at this time, the wireless network is not disconnected), and an IP packet filtering system (such as an Iptables command) is used to control all DNS query requests to be sent out from the data network, so as to execute DNS query operation for a target domain name through a DNS server corresponding to the data network.

It should be noted that, in the embodiment of the present application, the wireless network and the data network are both in a connected state, and only one path of data is selectively selected from the wireless network and the data network to be sent.

In some embodiments, the DNS query request includes a DNS message, and the step "sending the DNS query request to a corresponding DNS server through an accessed data network" may include the following steps:

acquiring a network identifier of an accessed data network and a matched IP address of a DNS server matched with the network identifier;

modifying the network configuration parameters of the DNS message into the network identifier;

modifying the address of the receiving end of the DNS message into the matched IP address;

and sending the DNS message to the corresponding DNS server based on the network identifier and the matched IP address.

The DNS message is divided into five segments, which are a header (header), a question to be queried (query), a response of the server (answer), an authority response (authority), and additional information (additional). The header section defines whether the message is a request or a response, and also defines whether other sections need to exist, and whether the sections need to be subjected to standard query or other conditions; the query section describes the question of the query, including the query type, the query class, and the domain name of the query.

Taking an iptables command as an example, the iptables command configuration is used, the DNS message (the message with the destination port of 53) is matched, and the DNS message is set to the network identifier netid of the data network (after each network is pulled up, one netid is in the android system, and when the data message is set to the netid of a certain network, the external network can be accessed from the network). Assuming that the network identifier netid of the data network is 0x064 and the DNS server allocated to the data network is 10.10.10.1, the following rule may be configured to let the DNS packet go out of the data network and access the DNS server of the data network:

the DNS packet is marked as a network identity netid of the data network, so that the DNS query is forwarded from the data network, which is set as follows:

iptables-mangle-A OUTPUT-p udp--dport 53-j MARK--set-mark 0x064

the destination IP addresses of the DNS messages are all converted into DNS servers (10.10.10.1) allocated by the data network, so that the DNS server inquired by the data network becomes a DNS server of the data network matched in advance. Because the DNS servers of the wireless network and the data network are not shared, the wireless network uses the DNS server of the wireless network, the data network uses the DNS server of the data network, and the DNS server of the wireless network may not be accessible from the data network because the DNS server of the system by default is the DNS server of the wireless network, the DNS server on the side of the data network needs to be queried. The settings were as follows:

iptables-t nat-A OUTPUT-p udp--dport 53-j DNAT--to-destination10.10.10.1

in some embodiments, the data network is pulled up for DNS query access only when the DNS query success rate of the data network is greater than the DNS query success rate of the wireless network. That is, before sending the DNS query request to the corresponding DNS server through the accessed data network, the following process may be further included:

acquiring second power consumption for performing DNS query through the data network, wherein the second power consumption is obtained based on information about success or failure of DNS query through the data network in historical time periods;

judging whether the second power forming rate is larger than the first power forming rate;

and if so, executing a step of sending a DNS query request to a corresponding DNS server through the accessed data network.

The second power generation may refer to the above calculation method of the first power generation, which is not described again.

103. And receiving a query result returned by the DNS server according to the DNS query request, wherein the query result comprises at least one target IP address corresponding to the target domain name.

Specifically, the DNS server is a DNS server matched to the data network. The DNS server may analyze a DNS request packet in the received DNS query request, thereby obtaining an IP address corresponding to the target domain name.

104. The destination IP address is stored in the electronic device.

Specifically, a target IP address corresponding to a target domain name obtained through DNS query is stored in the electronic device. Although the user does not access the target domain name at this time, the IP address corresponding to the target domain name (for example, a website that the user often needs to access) can be stored, so that the user can directly use the IP address when needing to access, and the user does not need to acquire the IP address when sending an access instruction, which greatly increases the response time of the user.

In some embodiments, after the target IP address is stored in the electronic device, a target network corresponding to the target IP address may also be accessed through the wireless network. At this time, if the wireless network is closed, all network accesses use the data network, and the consumed flow is very large, so that only the DNS message is queried through the data network, and other internet access requests are executed by using the wireless network, which can save the data flow and reduce the user cost.

In some embodiments, if a target network corresponding to a target IP address needs to be accessed through a line network, it needs to be determined that a wireless network is in a connected state, and only a corresponding DNS configuration or DNS server has a problem. That is, before accessing the target network corresponding to the target IP address through the wireless network, the following process may be further included:

sending a first data packet with a preset size to a network corresponding to a preset IP address through a wireless network;

judging whether a second data packet with a preset size returned by the network corresponding to the preset IP address is received or not;

and if so, executing a step of accessing a target network corresponding to the target IP address through the wireless network.

The preset IP address may be an IP address of a public network.

Specifically, when it is determined that the DNS query success rate corresponding to the wireless network is lower than the preset threshold, several ping messages for testing network connectivity are sent by the ping module of the wireless network to ping the IP address of the external network (e.g., 8.8.8.8, 114.114.114.114, etc.). If the ping server is up, the wireless network is considered to be problematic only for DNS queries.

For example, an Internet Control Message Protocol (ICMP) message is sent by an application ping, and is mainly used for testing the connectivity of the network, and if the network is unblocked, the returned information is Request from. However, there is a special case that: if the machine of the counterpart server turns off the ping service (including ping input and ping output), and the counterpart server is disconnected from the external network, the machine cannot ping it even if the machine is connected to the network.

In some embodiments, if a second data packet with a preset size returned by the network corresponding to the preset IP address is not received, it is determined that the wireless network connectivity is failed. At this time, the process may be ended, and information of network connectivity failure may be fed back to the electronic device.

In some embodiments, when it is determined that the wireless network connectivity fails, the target network corresponding to the target IP address may also be accessed through the data network. That is, when the connection of the wireless network fails to be smooth, the data network is selected to access the network server corresponding to the target IP address.

As can be seen from the above, in the domain name system DNS processing method provided in this embodiment, when detecting a DNS query request for a target domain name in a state where an electronic device is accessed to a wireless network, first success power for performing DNS query through the wireless network is obtained; if the first forming power does not reach the preset threshold value, sending a DNS query request to a corresponding DNS server through an accessed data network; receiving a query result returned by the DNS server according to the DNS query request, wherein the query result comprises at least one target IP address corresponding to a target domain name; the destination IP address is stored in the electronic device. According to the scheme, when the DNS query cannot be performed in a wireless network state, the data network is pulled up to execute the DNS query operation, so that the overall success rate of the DNS query is improved, the electronic equipment can surf the internet normally, and the network access efficiency is improved.

The method described in the above embodiments is further illustrated in detail by way of example.

Referring to fig. 2, fig. 2 is another schematic flow chart of a domain name system DNS processing method according to an embodiment of the present application.

Specifically, the domain name system DNS processing method may include the following steps:

201. when a DNS query request aiming at a target domain name is detected in a state that the electronic equipment is accessed to a wireless network, first success power for DNS query through the wireless network is obtained.

In the embodiment of the application, the first success rate can be obtained based on the information about whether the DNS query is successful or not through a wireless network (e.g., a Wi-Fi network) within the historical time period. For example, taking an example that a system installed in the electronic device is an android system, the android system has a module for counting a DNS query success rate, so as to count the success rate.

202. If the first success rate does not reach the preset threshold value, the electronic equipment obtains a second success rate for performing DNS query through a data network, and judges whether the second success rate is greater than the first success rate or not; if yes, go to step 203, otherwise, end the process.

In the embodiment of the present application, the second power consumption may be obtained based on information about whether DNS query is successful or not through a data network (including networks of 5G, 4G, 3G, and the like of different systems and other data networks) in a historical time period.

203. And the electronic equipment receives a query result returned by the DNS server according to the DNS query request, wherein the query result comprises at least one target IP address corresponding to the target domain name.

204. The electronic device stores the target IP address in a corresponding storage area.

Specifically, a target IP address corresponding to a target domain name obtained through DNS query is stored in the electronic device.

205. The electronic equipment detects the connectivity of the wireless network and determines whether the wireless network is connected or not; if yes, go to step 206; if not, go to step 207.

Specifically, whether the network is connected or not can be tested through the data packet. That is, the step of "detecting connectivity of a wireless network, determining whether connected"

if yes, determining to be in a connected state;

if not, determining that the communication is in an unconnected state.

The preset IP address may be an IP address of a public network.

Specifically, when it is determined that the DNS query success rate corresponding to the wireless network is lower than a preset threshold, several ping messages for testing network connectivity are sent to ping an IP address of an external network (i.e., a public network) through a ping module of the wireless network. If the ping server is up, the wireless network is considered to be problematic only for DNS queries.

For example, an ICMP message sent by an application ping is mainly used for testing the connectivity of a network, and if the network is unblocked, the returned message is Request from.

206. And the electronic equipment accesses a target network corresponding to the target IP address through the wireless network.

Specifically, when the wireless network is in a connected state, the data network is selected to access the network server corresponding to the target IP address. Because only the DNS message is inquired through the data network, and other internet access requests are executed by using the wireless network, the data flow can be saved, and the user cost is reduced.

207. The electronic device accesses a target network corresponding to the target IP address through a data network.

Specifically, when the wireless network is in a connection failure state, the data network is selected to access the network server corresponding to the target IP address.

As can be seen from the above, in the domain name system DNS processing method provided in this embodiment, when the DNS query cannot be performed in the wireless network state, the data network is pulled up to perform the DNS query operation, so as to improve the overall success rate of the DNS query, enable the electronic device to surf the internet normally, and improve the network access efficiency.

when the electronic equipment is in a state of accessing a Wi-Fi network and a DNS query request aiming at a target domain name is detected, acquiring first success power of DNS query through the Wi-Fi network, wherein the first success power is obtained based on information about success or failure of DNS query through the Wi-Fi network in a historical time period;

if the first success rate does not reach the preset threshold value, obtaining a second success rate for performing DNS query through the mobile data network, and if the second success rate is judged to be smaller than the first success rate, ending the process;

if the second power forming rate is larger than the first power forming rate, sending the DNS query request to a corresponding DNS server through an accessed mobile data network, wherein the Wi-Fi network and the mobile data network are both in a connection state;

storing the target IP address in the electronic device;

sending a first data packet with a preset size to a network corresponding to a plurality of preset IP addresses through a ping module of the Wi-Fi network, wherein the first data packet is used for testing network connectivity and judging whether a second data packet with the preset size returned by the network corresponding to the preset IP addresses is received or not;

if yes, determining that the Wi-Fi network is in a connected state, only corresponding DNS configuration or DNS server is in a problem, and accessing a target network corresponding to a target IP address through the Wi-Fi network;

if not, determining that the Wi-Fi network is in a connection failure state, and accessing a target network corresponding to the target IP address through the mobile data network.

2. The domain name system DNS processing method according to claim 1, wherein the DNS query request includes a DNS packet, and the sending of the DNS query request to a corresponding DNS server via an accessed mobile data network includes:

acquiring a network identifier of an accessed mobile data network and a matched IP address of a DNS server matched with the network identifier;

3. A domain name system DNS processing apparatus, comprising:

the device comprises a detection module and a processing module, wherein the detection module is used for acquiring first success power for performing DNS query through a Wi-Fi network when a DNS query request aiming at a target domain name is detected in a state that electronic equipment is accessed to the Wi-Fi network, and the first success power is obtained based on information about success or failure of DNS query through the Wi-Fi network in a historical time period;

the first sending module is used for acquiring second power generation rate for performing DNS query through a mobile data network if the first power generation rate does not reach a preset threshold value, and ending the flow if the second power generation rate is judged to be smaller than the first power generation rate; if the second power forming rate is larger than the first power forming rate, sending the DNS query request to a corresponding DNS server through an accessed mobile data network, wherein the Wi-Fi network and the mobile data network are both in a connection state;

a storage module for storing the target IP address in the electronic device;

the second sending module is used for sending first data packets with preset sizes to networks corresponding to a plurality of preset IP addresses through a ping module of the Wi-Fi network, and the first data packets are used for testing network connectivity;

the judging module is used for judging whether a second data packet with the preset size returned by the network corresponding to the preset IP address is received or not;

the access module is used for determining that the Wi-Fi network is in a connected state and only corresponding DNS configuration or a DNS server has a problem when the judgment module judges that the Wi-Fi network is in a connected state, and accessing a target network corresponding to a target IP address through the Wi-Fi network; if not, determining that the Wi-Fi network is in a connection failure state, and accessing a target network corresponding to the target IP address through the mobile data network.

4. The Domain Name System (DNS) processing apparatus according to claim 3, wherein the first sending module is configured to:

5. A storage medium having stored thereon a computer program, characterized in that, when the computer program is run on a computer, it causes the computer to execute the domain name system DNS processing method according to any one of claims 1 to 2.
