Problems solved by technology

In the prior art, if domain names in a certain area are blocked in the resolution system, their IP addresses will not be resolved, and the websites pointed to by these domain names will disappear from the Internet
Therefore, the existing technology lacks a solution to deal with root domain name resolution failure in the region

Abstract

The invention provides a method and system for providing root domain name analysis services. The method for providing the root name analysis services comprises the steps that DNS analysis records of a plurality of domain names in a preset region are obtained; an authorization information database of various levels of nodes of a DNS is established according to the analysis records; virtual root nodes for providing the root domain name analysis services are started and the virtual nodes respond to root domain name analysis requests in the preset region according to data in the authorization information database. According to the technical scheme, the DND authorization information database is established by using the DNS analysis records in the preset region, and the DNS authorization information database, serving as the data foundation of the virtual root nodes for providing the root domain name analysis services, provides the DNS root domain name analysis services in the region automatically. Thus, the internet risk caused by intra-region domain name analysis failures when an existing DNS system is used for conducting root domain name analysis is lowered.

Description

technical field [0001] The invention relates to the technical field of communication, in particular to a method and a system for providing root domain name resolution services. Background technique [0002] DNS is the abbreviation of Domain Name System (Domain Name System), which is a core service of the Internet. As a distributed database that can map domain names and IP addresses to each other, it can make people access the Internet more conveniently without using To remember the IP number string that can be read directly by the machine. [0003] Usually the general structure of the Internet host domain name is: host name. third-level domain name. second-level domain name. top-level domain name. The Internet's top-level domain name is registered and managed by the Internet Society Domain Name Registration Committee responsible for network address allocation, and assigns a unique IP address to each host on the Internet. [0004] figure 1 It is a hierarchical structure di...
