Abstract

The embodiment of the invention discloses a DNS resolution method, device and network system, which relate to the communication field and can simplify the DNS resolution process in the prior art. The method includes that the local domain name server receives the DNS domain name system resolution request sent by the client, wherein the DNS resolution request includes the first domain name and context information; the local domain name server cannot query the first domain name in the custom configuration and the obtained When the context information includes the second domain name, query the IP address corresponding to the second domain name in the context information in the custom configuration; the local domain name server feeds back the DNS resolution response containing the queried IP address to the client . Embodiments of the present invention are used for DNS resolution.

Description

technical field

[0001] Embodiments of the present invention relate to the communication field, and in particular to a DNS (English full name: Domain Name System, Chinese: Domain Name System) resolution method, device and network system. Background technique

[0002] In the existing network system architecture, when a client requests data content from a network server, it first needs to resolve the domain name requested by the client to an IP (English full name: Internet Protocol, Chinese: Internet Protocol) address to request data content based on the IP address. Specifically, the local domain name server receives the domain name resolution request (DNS request) sent by the client in the local network, recursively queries the upper-level domain name server, resolves the domain name to an IP address and carries it in the DNS response and feeds it back to the client; On the server, some domain names are resolved to other IP addresses through custom configuration, such as the ...
