Embodiment Construction

[0063] The technical solutions in the embodiments of the present application will be clearly and completely described below in conjunction with the accompanying drawings in the embodiments of the present application. Obviously, the described embodiments are only some of the embodiments of the present application, not all of them. Based on the embodiments of the present application, all other embodiments obtained by persons of ordinary skill in the art without creative efforts fall within the protection scope of the present application.

[0064] In order to improve the efficiency of domain name resolution and the security of the domain name, in the embodiment of this application, a domain name resolution method is designed. The method is to obtain the corresponding hash value based on the hash value of the domain name to be resolved when resolving the domain name to be resolved. The storage address of the domain name to be resolved is set by the value, and based on the obtained ...

Abstract

The embodiment of the present application discloses a domain name resolution method and device. The method is to determine the received resolution request message containing the domain name to be resolved sent by the terminal, obtain the domain name to be resolved contained in the resolution request message; calculate the domain name to be resolved Hash value, and based on the association between the preset hash value and the storage address of the domain name, determine the storage address of the domain name to be resolved corresponding to the hash value of the domain name to be resolved, wherein the domain name to be resolved is stored in a distributed manner ; Obtain configuration information of the domain name to be resolved based on the storage address, wherein the configuration information includes at least an IP address corresponding to the domain name; and send a resolution response message containing the configuration information to the terminal. In this way, the cumbersome steps of domain name resolution are reduced, and the efficiency of domain name resolution and the security of domain name are improved.

Description

technical field [0001] The present application relates to the technical field of communication, and in particular to a domain name resolution method and device. Background technique [0002] In existing Internet applications, network addressing and access are mainly performed through mutual mapping between Internet Protocol (Internet Protocol, IP) addresses and Domain Name System (Domain Name System, DNS) domain names. [0003] Wherein, the so-called DNS domain name is the name of a computer or computer group on the Internet formed by a series of dot-separated names, and a DNS domain name includes a root node and various sub-nodes of different levels (such as www.yunbaidu. com), used to identify a computer's electronic location, such as a geographic location, at the time of data transfer. In this way, the terminal can obtain the corresponding IP address by analyzing the DNS domain name, and access the server through the IP address. [0004] However, since each node of the ...
