Embodiment Construction

[0049]Reference will now be made in detail to the exemplary embodiments, examples of which are illustrated in the accompanying drawings. When the following description refers to the accompanying drawings, the same numerals in different drawings refer to the same or similar elements unless otherwise indicated. The implementations described in the following exemplary examples do not represent all implementations consistent with the present disclosure. Rather, they are merely examples of apparatuses and methods consistent with aspects of the present disclosure as recited in the appended claims.

[0050] figure 1 It is a flowchart of a domain name resolution method according to an exemplary embodiment. The method can be applied to terminal devices such as a mobile phone, a tablet computer, or a PC (Personal Computer, personal computer). Such as figure 1 As shown, the method includes step S11 to step S15.

[0051] In step S11, a configuration file is obtained from a private DN...

Abstract

The present disclosure relates to a domain name resolution method and device. The method includes: obtaining a configuration file from a private DNS server; sending domain name resolution requests to the default DNS server of the terminal device and at least one public DNS server respectively according to each domain name contained in the configuration file; according to the domain name resolution results returned by each DNS server Accuracy, determine the backup DNS server; when initiating a network request, if the configuration file contains the domain name corresponding to the network request, then perform domain name resolution on the domain name corresponding to the network request according to the configuration file, otherwise, use the backup DNS server to resolve the domain name corresponding to the network request DNS. The present disclosure can meet the domain name resolution requirements facing the open network under the premise of reducing the risk of domain name hijacking as much as possible, and has lower bandwidth requirements for private DNS servers and lower maintenance costs.

Description

technical field [0001] The present disclosure relates to the field of communication technology, and in particular to a domain name resolution method and device. Background technique [0002] Before the client initiates a network request to the server, it needs to first send a domain name resolution request to the DNS (Domain Name System, Domain Name System) server to obtain the IP (Internet Protocol, Internet Protocol) address corresponding to the domain name. The DNS server may include some wrong correspondence between domain names and IP addresses intentionally or under attack. Returning the wrong correspondence between domain names and IP addresses to the client will cause DNS hijacking and may cause losses to users. [0003] In related technologies, usually the developer of the application builds a private DNS server by itself, and ensures the reliability of the DNS resolution process by means of encryption. In this manner, before initiating a network request, the clien...
