DOMAIN NAME PARSING METHOD, AUTHORITATIVE DOMAIN NAME SERVER AND LOCAL DOMAIN NAME SERVER

摘要

A domain name parsing method, an authoritative domain name server and a local domain name server, wherein the method comprises: receiving a domain name parsing request sent by a local domain name server, the domain name parsing request comprising a target sub-domain name under a target domain name (S11); and querying a domain name parsing record of the target sub-domain name in domain name configuration information of the target domain name, and feeding back the queried domain name parsing record to the local domain name server to enable the local domain name server to acquire a domain name parsing result of the target sub-domain name according to an external authoritative server indicated by the domain name parsing record that was fed back (S13). The method is capable of accelerating the switching process of an authoritative domain name server.
