Abstract

The invention discloses a domain name resolution method, an authoritative domain name server and a local domain name server. The method comprises the steps of receiving a domain name resolution request sent by the local domain name server, wherein the domain name resolution request comprises a target sub-domain name under a target domain name; querying a domain name resolution record of the targetsub-domain name in the domain name configuration information of the target domain name; and feeding back the domain name resolution record obtained through query to the local domain name server, sothat the local domain name server obtains a domain name resolution result of the target sub-domain name according to an external authorization server pointed by the fed back domain name resolution record. According to the technical scheme provided by the invention, the switching process of the authoritative domain name server can be accelerated.

Description

technical field [0001] The invention relates to the technical field of the Internet, in particular to a domain name resolution method, an authoritative domain name server and a local domain name server. Background technique [0002] In the current domain name resolution process, after receiving a domain name access request from a user, the local domain name server can generate a corresponding domain name resolution request for the domain name access request, and query the root server for the domain name resolution result of the corresponding domain name. According to the type of domain name to be resolved, the root server can feed back the information of the authoritative domain name server to the local domain name server. Subsequently, the local domain name server can obtain the corresponding domain name resolution result from the authoritative domain name server. [0003] In practical applications, it is very likely that the current authoritative domain name server provid...
