Problems solved by technology

According to the existing authoritative domain name resolution service process, if the domain name queried by the user is spelled correctly (that is, it can be accurately matched with a registered domain name), the authoritative response generated by the authoritative server will contain the A record type information corresponding to the domain name (that is, the domain name and its host IP address); on the contrary, if the spelling is wrong (that is, it cannot be exactly matched with any registered domain name), the authoritative response will not contain any A record type information, which will cause the user's visit to fail

Embodiment Construction

[0019] In order to make the above objects, features and advantages of the present invention more obvious and understandable, the present invention will be further described below through specific embodiments and accompanying drawings.

[0020] The authoritative domain name server in the present invention, in addition to storing the authoritative information of the mapping relationship between the registered domain name and its host IP address in the form of A record type, will also store the registered domain name and all other unregistered domain names in the form of SNAME record type Authoritative information on the mapping relationship between similar domain names (such as similar strings, similar semantics, similar phonetics, etc.)

[0021] If the domain name queried by the user is spelled correctly (that is, it can be accurately matched with a registered domain name), the authoritative answer generated by the authoritative domain name server will contain the A record type ...

Abstract

The invention relates to a novel authoritative domain name resolution service method and device. First, in the authoritative domain name server, the authoritative information of the mapping relationship between the registered domain name and its host IP address is stored in the form of A record type, and the relationship between the registered domain name and all other unregistered similar domain names is stored in the form of another resource record type Authoritative information of the mapping relationship; if the spelling of the domain name queried by the user is correct, the authoritative response contains the A record type information corresponding to the domain name; otherwise, check whether there is the other resource record type information corresponding to the domain name, and if so Then the authoritative answer includes the type information of the other resource record corresponding to the domain name, otherwise, the domain name is automatically matched with all registered domain names and an authoritative answer is generated. The invention enables the user to access the target host without knowing the precise domain name of the target host, thereby effectively improving the domain name access experience of the user.

Description

technical field [0001] The invention belongs to the field of network technology and domain name resolution technology, and in particular relates to a novel authoritative domain name resolution service method and device. Background technique [0002] Domain name resolution service is a key basic service of the Internet, responsible for helping users realize the mapping and resolution process between domain names and IP addresses. Domain name resolution service usually requires the participation of two types of components, that is, recursive domain name server and authoritative domain name server. figure 1 shown. When an Internet user needs to access a certain target host, (1) first, the user needs to initiate a domain name query request for the target host to the recursive domain name server. If the recursive domain name server locally caches the authoritative response to the domain name query, then (2) directly returns the authoritative response to the user; otherwise (3) ...
