DNS intelligent scheduling method based on a user strategy

Abstract

The invention particularly relates to a DNS intelligent scheduling method based on a user strategy. According to the DNS intelligent scheduling method based on the user strategy, a user strategy module and a user strategy database are newly added in a DNS system; The IP library is classified according to operators and regions; After the user configures the line type and maps the domain name, the user strategy module automatically reads strategy information and stores the domain name and the corresponding regional operator combination into a database; And when the domain name resolution requestreaches the DNS system, the user strategy module inquires a corresponding regional operator according to the domain name, narrows the range of inquiring the IP library, and then accurately positionsthe IP library of the request source from the effective IP library so as to return different resolution results. According to the DNS intelligent scheduling method based on the user strategy, the problem that efficiency is low due to the fact that a large number of invalid IP libraries are frequently queried in a traditional DNS intelligent scheduling method is solved, the effective IP libraries are screened out by additionally arranging the user strategy module and the user strategy database, the query frequency is reduced, and therefore the analysis efficiency is greatly improved.

Description

technical field [0001] The invention relates to the technical field of DNS resolution, in particular to a user strategy-based DNS intelligent scheduling method. Background technique [0002] DNS (Domain Name System) is the Domain Name System, a distributed database on the World Wide Web that maps domain names and IP addresses to each other, enabling users to access the Internet more conveniently without having to remember IP numbers that can be directly read by machines. Through the domain name, the process of finally obtaining the IP address corresponding to the domain name is called domain name resolution (or host name resolution). The DNS protocol runs on the UDP (User Datagram Protocol, User Datagram Protocol) protocol, using port number 53. It is composed of a resolver and a domain name server. A domain name refers to a server that saves the domain names and corresponding IP addresses of all hosts in the network, and has the function of converting domain names into IP ...

Problems solved by technology

However, because the IP library may come from the whole country or even the whole world, the classification of regions is very large, and it will take a lot of time to query from each IP library. In addition, the national IP library list is often changed, which leads to relying on this method of IP library It needs to be updated frequently to synchronize the relevant information of the IP address, which greatly reduces the efficiency of parsing
