Problems solved by technology

However, if the current load of the server corresponding to the IP address returned to the user is heavy, it will inevitably make the server respond slowly. Correspondingly, the speed of the terminal device to access the network is also slow, which reduces the user's network experience.

Embodiment 1

[0021] figure 1 It is a flow chart showing the domain name resolution method according to Embodiment 1 of the present invention. The method can be performed eg on a DNS server.

[0022] refer to figure 1 , in step S110, receiving a domain name resolution request sent by the terminal device.

[0023] When a user accesses the network through a terminal device, he needs to input the domain name of the website to be visited, such as www.le.com, to access the server of the website. The user first sends a domain name resolution request to the DNS server through the terminal device, and the domain name resolution request is used to resolve the domain name through the DNS server.

[0024] In step S120, domain name information is obtained from the domain name resolution request, and IP addresses of multiple servers corresponding to the domain name information are obtained.

[0025] In a specific implementation manner, after receiving the request for domain name resolution, it may f...

Embodiment 2

[0031] figure 2 is a flowchart showing a domain name resolution method according to Embodiment 2 of the present invention, and the embodiment can be regarded as figure 1 Another specific implementation scheme of . available in as Figure 4 The method is executed on the domain name resolution device shown.

[0032] refer to figure 2 , in step S210, receiving a domain name resolution request sent by the terminal device.

[0033] In step S220, domain name information is obtained from the domain name resolution request, and IP addresses of multiple servers corresponding to the domain name information are obtained.

[0034] Here, the processing methods of step S210 and step S220 are the same as those of step S110 and step S120 in the first embodiment. For details, please refer to the above steps of S110 and S120, which will not be repeated here.

[0035] Wherein, steps S230 and S240 may be refinements of step 130 in the first embodiment above, specifically as follows:

Embodiment 3

[0047] Based on the same technical idea, image 3 It is a logical block diagram showing a domain name resolution device according to Embodiment 3 of the present invention. It can be used to execute the flow of the domain name resolution method described in the first embodiment.

[0048] refer to image 3 , The domain name resolution device includes: a request receiving module 310 , a domain name and address obtaining module 320 , a server selecting module 330 and an address sending module 340 .

[0049] The request receiving module 310 is configured to receive the domain name resolution request sent by the terminal device.

[0050] The domain name and address obtaining module 320 is configured to obtain domain name information from the domain name resolution request, and obtain IP addresses of multiple servers corresponding to the domain name information.

[0051] The server selecting module 330 is used for selecting the server with the least load among the plurality of ser...

Abstract

The invention provides a domain name resolution method and device, wherein the domain name resolution method comprises: receiving a domain solution request sent by a terminal device; obtaining domain information from the domain solution request, and the IP addresses of a plurality of servers corresponding to the domain information; selecting a server having a smallest load from the plurality of servers; and sending the IP address of the server having a smallest load to the terminal device, allowing the terminal device to access the server having a smallest load. The method and device feed back the IP address of the server having a smallest load to the terminal device when the terminal device sends a domain name resolution request, thereby improving the access network speed of the terminal device, and improving user network experiences.

Description

technical field [0001] The invention relates to Internet technology, in particular to a domain name resolution method and device. Background technique [0002] The Domain Name System (Domain Name System, DNS) is the basic protocol of the Internet, which is used to complete the translation from the domain name to the Internet Protocol (IP) address of the Internet. The DNS server has the following two functions: one is to save the domain names and corresponding IP addresses of all hosts in the network; the other is to convert domain names into IP addresses. Among them, the process of mapping a domain name to an IP address is called "domain name resolution". A domain name can correspond to one or more IP addresses. [0003] Usually, when a user enters the domain name of a certain website in the address bar of the browser, the browser sends the domain name to a preset DNS server. The DNS server resolves the domain name to obtain an IP address. Most of the domain names of som...
