Embodiment Construction

[0016] In order to make the purpose, technical solution and advantages of the present application clearer, the implementation manners of the present application will be further described in detail below in conjunction with the accompanying drawings.

[0017] With the rapid development of the Internet, the network environment is becoming more and more complex. Various factors such as lack of interconnection, regional ISP geographical limitations, and limited export bandwidth have caused the website to be inaccessible regionally. Therefore, the traditional centralized deployment of resource nodes can no longer satisfy users. In order to ensure that users in different regions can get a good experience when visiting the website, many content providers will adopt a distributed deployment method to deploy resource nodes in different regions, which also leads to the existence of the same domain name distributed in different regions. Multiple origin stations in different regions, and d...

Abstract

The invention discloses a method for selecting a DNS server. The method includes: obtaining a target data access request, and analyzing the target data access request to obtain a carried target domain name; according to the target historical analysis record corresponding to the target domain name, Determining a target DNS server among the default DNS server and the at least one alternative DNS server, so that the target DNS server resolves the target domain name; receiving the resolution result fed back by the target DNS server, and The target data access request is sent to the target source site pointed to by the parsing result, and the target historical parsing record is updated based on the response result of the target source site. The technical solution provided by this application can automatically select an appropriate DNS server for a domain name.

Description

technical field [0001] The invention relates to the technical field of the Internet, in particular to a method for selecting a DNS server and a proxy server. Background technique [0002] With the rapid development of the Internet, the network environment is becoming more and more complex, and the traditional centralized deployment of resource nodes can no longer meet the needs of users. In order to ensure that users in different regions can get a good experience when visiting websites, many content providers will use distributed The way of deployment is to deploy resource nodes in different regions, which also leads to multiple origin sites for the same domain name. Before the user sends an access request for data resources, if the destination IP address cannot be obtained from the local host table, the locally configured DNS server needs to perform domain name resolution to obtain the server IP corresponding to the accessed domain name. Generally speaking, the user The de...
