Abstract

The invention discloses a method for resolving a root domain name. The method comprises the following steps that: a root server stores at least NS records of a root, a TLD, and a second-level domain name server; the root server is divided into two categories, A and B, according to the way of obtaining an NS record source of a DNS zone, and implements differentiated data management rules for two types of data; the root server adds a backup service record to verify the security level of the domain name to be queried; and the root server is divided into a main root server and a mirror root server, and implements different mirroring rules. According to the method for resolving the root domain name, the root server provides stored records of the roots and N-level subdomain authoritative queries, and ensures the record retention and update of the root independent operation, thereby providing localized root mirroring rules, reducing resolution latency, and improving security and 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...
