dns security system and its troubleshooting method

Abstract

The invention provides a DNS security system and a fault handling method thereof. The DNS security system includes: at least one client configured to initiate a DNS request; a root node configured to provide authorization information for the DNS request; an authorization information database configured to store all DNS requests and corresponding authorization information in a specified area; a virtual The root node is configured to invoke corresponding authorization information from the authorization information database to provide resolution services for corresponding clients when DNS resolution failure occurs on the root node. The safety and stability of DNS resolution can be improved by adopting the invention.

Description

technical field

[0001] The invention relates to the field of Internet applications, in particular to a DNS security system and a fault handling method using the DNS security system. 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 it easier for people to access the Internet without having to remember An IP number string that can be read directly by the machine.

[0003] 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 top-level domain name of the Internet is registered and managed by the Internet Society Domain Name Registration Committee responsible for network address allocation. It also assigns a unique IP address to each host on the Internet.
