Embodiment Construction

[0056] The domain name resolution method and device provided in the embodiments of the present application will be described in detail below in conjunction with the accompanying drawings.

[0057] figure 2 It is a flow chart of a domain name resolution method provided in the embodiment of this application, the method includes the following steps:

[0058] S201. Obtain a domain name resolution request, determine one or more domain name resolution target servers according to a preset distribution strategy, and distribute the domain name resolution request to the domain name resolution target server;

[0059] S202. Receive a domain name resolution response returned by each domain name resolution target server;

[0060] S203. Select one of all received domain name resolution responses according to a preset ruling policy as a target response corresponding to the domain name resolution request.

[0061] Assuming that the domain name to be resolved is A, according to the embodimen...

Abstract

The embodiment of the invention discloses a domain name analysis method and device. The domain name analysis method comprises the steps of: selecting one or more domain name analysis servers from multiple domain name analysis servers, taking one or more domain name analysis servers as target domain name analysis servers, respectively distributing the same domain name analysis request to each target domain name analysis server, analyzing the same domain name to be analyzed through the target domain name analysis servers, so that multiple domain name analysis responses are obtained, selecting one domain name analysis response from the multiple domain name analysis responses, and taking the domain name analysis response as the target response. Compared with the condition that domain name analysis is carried out by fixed adoption of a domain name analysis server for a long time in the prior art, the embodiment of the invention can avoid the condition that a large number of domain names are wrongly analyzed when a certain domain name analysis server has a security problem, increase the accuracy rate of the domain name analysis result, and improve the access security.

Description

technical field [0001] The present application relates to the technical field of network communication, in particular to a domain name resolution method and device. Background technique [0002] In the field of network communication, Domain Name System (DNS) is a distributed database responsible for providing mapping between domain names and IP addresses. It is currently the largest and most complex distributed hierarchical database system in the world. Domain name resolution (DNS resolution) is the process of finding the IP address corresponding to any domain name that the user wants to visit according to the mapping relationship between the domain name and the IP address provided in the DNS system, so that the user does not need to remember the information that can be directly read by the machine The IP number string can conveniently access the Internet only based on the easier-to-remember domain name. [0003] refer to figure 1 A DNS system architecture shown, when the ...
