Abstract

The embodiments of the invention disclose a method and a device for processing domain name requests. By extending the type of a domain name request or configuring an equipment type of user equipment in the domain name request, a DNS server can sense the request intention or the equipment type of the user equipment and further returns an A record and / or an AAAA record which is required by the user equipment and adapts to the network condition to the user equipment, so that the blindness of the DNS response is reduced, unnecessary operations of query and generation of the A record or the AAAA record are avoided, unnecessary network address translation operation is avoided and the performance requirement for the DNS server and an NAT server is reduced. Besides, an access gateway does not need to assign domain name requests to different DNS servers for user equipment of different types, so that the configuration complexity and distribution processing complexity of DNS server distribution of the access gateway are reduced and the network deployment is convenient.

Description

technical field [0001] The invention belongs to the communication field, and in particular relates to a method and equipment for processing domain name requests. Background technique [0002] With the development of Internet technologies, IPv4 (Internet Protocol version 4, Internet Protocol version 4) addresses have been exhausted, and more and more users migrate to IPv6 (Internet Protocol version 6, Internet Protocol version 6) networks. However, due to historical reasons, user equipment connected to the network may be an IPv4 device with an IPv4 address, an IPv6 device with an IPv6 address, or a dual-stack device with both an IPv4 address and an IPv6 address; , the network side includes not only IPv6 servers with IPv6 addresses, but also a large number of IPv4 servers with only IPv4 addresses but no IPv6 addresses. [0003] In order to enable IPv6 devices to access IPv4 servers, NAT64 (Network Address Translation: IPv6 to IPv4, IPv6 to IPv4 network address translation) se...
