Problems solved by technology

[0012] 2. The local DNS server does not contain the authoritative domain of 163.com, and there is no corresponding www record, so the request is forwarded to the root domain name server (assuming a.root-servers.net.)
[0022] 2. The authoritative DNS administrator cannot clearly know the IP address of the end user, which will affect the authoritative DNS administrator's inability to accurately dispatch the user's request to the optimal application service

Embodiment Construction

[0062] The following clearly and completely describes the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only some of the embodiments of the present invention, not all of them. Based on the embodiments of the present invention, all other embodiments obtained by persons of ordinary skill in the art without making creative efforts belong to the protection scope of the present invention.

[0063] Such as figure 1 As shown, a domain name resolution method in which the authorized domain name server directly responds, including:

[0064] Step S100, the application module sends a DNS resolution request, and the DNS resolution request carries a domain name;

[0065] Step S200, the enhanced DNS request module receives the domain name system DNS resolution request sent by the application module, resolves the domain name carried in the DNS resolution request, and determines whether the domain name is in the whitelist;

Abstract

A domain name resolution method authorizing direct response of a domain name server includes the steps that an application module sends out a DNS resolution request which carries a domain name; a reinforcing DNS request module receives the DNS resolution request sent by the application module, resolves the domain name carried by the DNS resolution request and determines whether the domain name exists in a white list or not; the reinforcing DNS request module sends a query request to the DNS server and submits a resolution result returned by the DNS server to the application module. The domain name resolution method can ensure accuracy and reliability of the DNS resolution result.

Description

technical field [0001] The invention relates to a domain name resolution method and system for directly responding to an authorized domain name server. Background technique [0002] In the IP (Internet Protocol, Internet Protocol) network, the Domain Name System (DNS) is one of the most critical basic services of the Internet, providing fundamental support for many network applications. (Domain Name) and the network-recognizable IP address for conversion. The conversion between domain name and IP address is called domain name resolution, and the network host that performs domain name resolution can be called DNS server. Through the query service of the domain name system DNS server, the entrance of the required site or resource can be found, and then the site or resource can be accessed. [0003] In the prior art, DNS provides three domain name resolution methods: local query, cache query and iterative query. [0004] If the user accesses the Internet through an ISP (Inte...
