A method for pan-root domain name resolution

Abstract

The invention discloses a pan-root domain name resolution method. The method includes: the pan-root server at least saves the NS records of the root, TLD and secondary domain name servers; There are two types of data, A and B, and differentiated data management rules are implemented; a backup service record is added on the pan-root server to verify the security and reliability level of the domain name to be queried; the pan-root server is divided into main pan-root servers. The root server and the mirror pan-root server implement different mirroring rules. The invention provides the record preservation of the root and N-level subdomain authoritative query through the pan-root server, ensures the record preservation and update of the independent operation of the pan-root, provides localized root mirroring rules, reduces parsing delay, and improves security and performance. degree of stability.

Description

technical field

[0001] The invention relates to the field of domain name resolution of Internet basic services, in particular to a method for pan-root domain name resolution. Background technique

[0002] At present, network communication entrances must pass through DNS (Domain Name System, Domain Name System). The World Wide Web is a distributed database that maps domain names and IP addresses to each other, enabling users to access the Internet more conveniently, without having to remember that it can be directly accessed by a machine. The read IP number string, through domain name resolution, the client will access the IP address corresponding to the domain name.

[0003] The domain name architecture is a tree structure, iterative query, such as figure 1 As shown, from top to bottom, the root server manages the address of the TLD, the TLD domain name server manages the address of the second-level domain name, the second-level domain name server manages the third-level do...
