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] like 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 cor...

The invention provides an intelligent analysis method of a domain name system (DNS), a poking measurement device and a system, and relates to the DNS analysis field so as to solve the technical problems that DNS analysis results of an authorized server in the prior art are not accurate enough. The method includes the steps that the poking measurement device receives recursion requests launched by a first local DNS server which provides analysis service for a terminal user, the recursion requests comprise domain names to be accessed, the poking measurement device and the terminal user have the same network exit, the poking measurement device looks up internet protocol (IP) addresses corresponding to the domain names to be accessed in an analysis list of the poking measurement device, the analysis list saves the IP addresses selected through poking measurement in advance and corresponding to the domain names, the poking measurement device sends the IP addresses looked up to the first local DNS server, and the first local DNS server sends the IP addresses to the terminal user. The intelligent analysis method, the poking measurement device and the system can optimize the DNS analysis results of the authorized 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. In order 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 use...
