Abstract

The invention discloses a method for resolving a domain name, system and server. The method comprises the steps of: a terminal user initiating a domain name query request to a local domain name system (LDNS) server; when the LDNS server inquires a local cache and is not hit, executing the following steps: the LDNS server initiating a query request to an authorized DNS server of the domain name by recursive resolution; the LDNS server receiving the query result from the authorized DNS server; when the query result is abnormal, the LDNS server initiating a query request for the domain name to a public DNS server via an automatic forwarding mechanism; and the LDNS server returning the resolution result received from the public DNS server to the terminal user, and saving the resolution result into the local cache.

Description

technical field [0001] The present application belongs to the communication field, and more specifically, the present application relates to a method, system and server for resolution by a public DNS server. Background technique [0002] Domain Name System (DNS) is a distributed database on the Internet that maps domain names and IP addresses to each other. It is the most basic and core service in the Internet architecture. DNS technology can enable users to access the Internet more conveniently, without having to remember the IP number string that can be directly read by the machine. The process of finally obtaining the IP address corresponding to the host name through the host name is called domain name resolution (or host name resolution). [0003] DNS technology provides fundamental support for many network applications. Classified according to functions, DNS servers can be roughly divided into authoritative DNS servers and recursive DNS servers. An authoritative DNS ...
