Abstract
A domain name resolution method includes: obtaining a domain name resolution request packet; caching the obtained domain name resolution request packet to a first cache area; modifying, in the first cache area, header data included in the cached domain name resolution request packet, to obtain header data of a domain name resolution reply packet corresponding to the cached domain name resolution request packet; extracting a requested record type and a domain name to be resolved in the cached domain name resolution request packet; searching a second cache area for pre-cached reply data that corresponds to the extracted domain name and that belongs to the extracted record type; and combining the pre-cached reply data with the domain name resolution request packet obtained through modification, to obtain a domain name resolution reply packet.
