Embodiment Construction

[0072] In order to make the technical problems, technical solutions and advantages to be solved by the embodiments of the present invention clearer, the following will describe in detail with reference to the drawings and specific embodiments.

[0073] Such as figure 1 As shown, it is an embodiment of a method for intelligent resolution of a domain name system DNS according to the present invention, including:

[0074] Step 11, the first local DNS server receives the domain name resolution request of the terminal user; the domain name resolution request includes a domain name to be accessed; for example, the terminal user needs to visit the SINA website; initiates a domain name resolution request to the first local DNS server, the The parsing request includes: www.sina.com.

[0075] Step 12, the first local DNS server determines whether the IP address corresponding to the domain name to be accessed is stored locally;

[0076] Step 13, if the first local DNS server saves the ...

Abstract

The invention provides an intelligent resolution method, dial testing device and system of a domain name system DNS, relates to the field of DNS resolution, and is invented to solve the technical problem that the DNS resolution result of an authorization server is not accurate enough in the prior art. The method includes: the dial-up testing device receives a recursive request initiated by a first local DNS server that provides resolution services for end users; the recursive request includes a domain name to be accessed; the dial-up testing device has the same network exit as the terminal user The dial test device searches the IP address corresponding to the domain name to be accessed in its resolution table, and the resolution table saves the IP address corresponding to the domain name through dial test in advance; the dial test device sends to the first A local DNS server sends the found IP address, and the first local DNS server sends it to the terminal user. The invention can optimize the DNS resolution result of the authorization server.

Description

technical field [0001] The invention relates to the field of DNS domain name resolution, in particular to a domain name system DNS intelligent resolution method, dial testing device and system. Background technique [0002] DNS (Domain Name System, Domain Name System), as an integral part of Internet services, provides a mapping relationship between domain names and IPs. With the development of the Internet, due to resource and system barriers between different operators' networks, the interconnection link resources between the networks are becoming increasingly tense, which greatly affects the network access rate across operators. To solve this kind of problem, large-scale ICP (Internet Content Provider, Internet Content Service Provider) will set up servers in the networks of different operators, and at the same time guide users to access the content in the same network nearby through the judgment of domain name resolution. This kind of technology that guides users to acc...
