摘要

Disclosed are a domain name resolution method, a domain name cache server and a final domain name server. The method comprises: a domain name cache server establishing a connection with a final domain name server through address information about the final domain name server; and acquiring all of the domain name record information about a predetermined domain name from the final domain name server, so as to determine a domain name resolution result of the predetermined domain name according to all of the domain name record information, wherein all of the domain name record information is a correlation between the predetermined domain name and different IP addresses. By applying the present invention, a domain name cache server can determine a domain name resolution result according to a current link condition, thereby solving the problem in the related art that a domain name resolution is unable to be conducted according to a real network situation when a user initiates a domain name request due to the fact that a domain name cache server caches an old domain name record.
