Problems solved by technology

The Internet is a global network. Clients may come from different operators, different countries and regions, and different network environments. The judgments and settings made by authoritative servers for thousands of clients are subjective, and there is no guarantee that the returned data is accurate. optimal

Embodiment Construction

[0047] Such as figure 1 As shown, users A and A' are two Internet users located on the Internet, A network, B network, C network and D network are four local networks in the Internet, and the detector is a detector placed on the A network. machine, recursive RDNS is a recursive server, authoritative ADNS is an authoritative server placed in the example.com zone of network D, site 1 on network B and site 2 on network C are two mirror sites of the example.com application. If the user wants to access the application of example.com, his terminal will resolve the domain name to the DNS system. The specific steps of the domain name resolution method for data optimization are as follows:

[0048] (1) User A requests example.com to resolve;

[0049] (2) After the recursive domain name server RDNS receives the request, it sends a certain type of iterative resolution request for example.com to the relevant authoritative server, obtains authoritative data, and then returns it to user A...

Abstract

The invention discloses a domain name resolution method and system for data optimization. By arranging and selecting as many detection points as possible close to the target user, the DNS data obtained by recursive domain name server analysis is detected and evaluated, and the detection results are fed back to the recursive domain name. The server is used to improve the quality of cached data, so that the DNS server can serve users as well as possible, and provide users with safe and stable DNS services.

Description

technical field [0001] The invention belongs to the technical field of DNS system security, and relates to a domain name resolution method and system for data optimization. Background technique [0002] As an important infrastructure of the Internet, the Domain Name System (DNS) has always provided key basic services for the operation of the global Internet. The security and stability of the DNS system is very important to the Internet. [0003] The domain name resolution server is an important role in the DNS system. It forwards and receives the client's domain name resolution request, makes an iterative query to the authoritative server, and finally returns the resolution data to the client. Generally speaking, if a domain name has multiple resource records of a certain type, the returned parsing data is a resource record set consisting of multiple resource records. [0004] With the development of DNS, a new mode of operation has emerged. The operator of the authoritati...
