DNS intelligent resolution method based on outlet network

Abstract

A DNS intelligent resolution method based on an outlet network comprises the steps of adding customized configuration resolution information into a DNS service configuration; adding an intelligent resolution module into a DNS analysis program; and when data which are requested by a user DNS arrive a server, performing resolution on the user according to the customized configuration information, acquiring a corresponding service provider IP address, and returning the service provider IP address to a user. According to the DNS intelligent resolution method, only modification of a domain name DNS server to related server configuration is required, and no other hardware equipment is required. According to the DNS intelligent resolution method, an optimal DNS resolution result can be intelligent selected for the user, particularly in a multipath environment, thereby greatly improving a network accessing speed. The DNS intelligent resolution can be freely started and stopped by the user, thereby realizing total independence, high stability, high reliability and no conflict with other configuration. According to the DNS intelligent resolution method, intelligent resolution in accessing Internet by an internal network is realized, thereby increasing the resolution speed for a domain name; and a fastest service operator IP is returned to the user, thereby increasing network accessing speed by the user.

Description

technical field [0001] The invention relates to the technical field of DNS domain name resolution, in particular to an egress network-based DNS intelligent resolution method. Background technique [0002] Following the division of the former China Telecom Group into the north and the south, China Telecom and China Netcom Group were established in 2002. Therefore, the backbone network of the Internet was also divided into two, with China Netcom in the north and China Telecom in the south. Since then, the users of China Telecom and China Netcom have been extremely slow to access each other, and sometimes even cannot access each other. This phenomenon has seriously affected the number of visits to the website and the experience of users, and some commercial websites have suffered greatly from it. The reason for this phenomenon is that the speed of the North-South network is mutually restricted, and the exchange of visits is very slow. It can be understood that the difficulty o...

Problems solved by technology

All of the above have certain limitations, because the IP addresses of many intranet users are generally private addresses, which cannot be used to determine the operator they belong to, let alone resolve and return which operator's IP according to which operator they belong to. Address, forwarding by domain name cannot be fully configured, and the number of domain names is too large to configure and forward a large number of domain names
