Kind Code:
A1
Abstract:
Disclosed are a method and a device for processing a domain name request. By extending a type of a domain name request or configuring a device type of a user equipment in the domain name request, a DNS server can sense a request intention or the device type of the user equipment, and can further return, to the user equipment, an A record and/or an AAAA record required by the user equipment and adapted to network condition, so that the blindness of a DNS response is reduced, unnecessary operations of querying and generating the A record or the AAAA record are avoided, unnecessary operations of network address translations are avoided, and performance requirements for the DNS server and an NAT server are reduced. In addition, an access gateway does not need to allocate a domain name request to different DNS servers for user equipments of different types, so that the configuration complexity and the allocation processing complexity of allocation of DNS servers by the access gateway are reduced, thereby facilitating network deployment.
