Problems solved by technology

According to the existing domain name resolution service process, if the domain name queried by the user is real, the Answer part of the answer received by the user will contain the host IP address corresponding to the domain name to guide the user to initiate access; on the contrary, if the domain name If the domain name does not exist, the response received by the user will not contain any host IP address information, which will cause the user's access to fail

Embodiment (1

[0025] Embodiment (1): Return information containing the IP address of the name search server by the authoritative domain name server

[0026] First, the user initiates a domain name query to the recursive domain name server. If the recursive domain name server locally caches the response information about the domain name query, it will directly return the response information to the user; otherwise, the recursive domain name server will initiate a corresponding iterative domain name query to the upper-level authoritative domain name server.

[0027] When the authoritative domain name server receives the domain name query request sent by the recursive domain name server, it first checks whether the domain name actually exists (that is, whether it is correct). If it exists, the Answer part of the response message returned by the authoritative domain name server to the recursive domain name server will contain the real host IP address corresponding to the domain name; if it does...

Embodiment (2

[0030] Embodiment (2): The recursive domain name server returns the response information containing the newly added flag

[0031] First, the user initiates a domain name query to the recursive domain name server. If the recursive domain name server locally caches the response information about the domain name query, it will directly return the response information to the user; otherwise, the recursive domain name server will initiate a corresponding iterative domain name query to the upper-level authoritative domain name server until it receives a query about the domain name Authoritative response, the authoritative response is cached this time.

[0032] If the Answer part of the authoritative response message received by the recursive domain name server is not empty and there is no corresponding name search OPT record in the Additional part, it means that the domain name really exists, and the recursive domain name server will directly return the answer message to the user; o...

Embodiment (3

[0034] Embodiment (3): Example of matching process

[0035] When the name search server receives the visit initiated by the user, it first analyzes the domain name that the user wants to query according to the visit. For example: Assuming that the user queries "http: / / Beijing Institute of Technology. China", since the domain name "Beijing Institute of Technology. China" has not been registered, the background of the name search server will match the domain name keyword "Beijing Institute of Technology". The present invention does not limit the specific matching method. For example, the title information of the existing website homepage can be crawled offline on a large scale to form a mapping library of URL and title keywords. The record form of the library is such as: "URL-title keywords", And through large-scale anchor text statistics, the above mapping is further improved. The records in the improved mapping library are in the form of: "URL—[title keyword, anchor text keywo...

Abstract

The invention relates to a novel domain name resolution service method and device supporting name search. The method includes: 1) adding a name search server in the domain name resolution service system, the user first initiates a domain name query to a recursive domain name server and an authoritative domain name server, and when the domain name inquired does not exist, a name search server is added in the Answer part of the response message 2) After receiving the response message containing the IP address information, the user decides independently whether to initiate access to the provided IP address of the name search server; if the user chooses to continue to initiate access based on the IP address of the name search server, then The name search server matches the non-existent domain name queried by the user, and guides the access initiated by the user to the domain name with the highest matching degree, so as to realize access to the target host. The present invention can realize the user's fuzzy access to the target host, and can effectively improve the addressing 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 domain name resolution service method and device supporting name search. 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 a user needs to access a target host, (1) first, the user needs to initiate a domain name query for the target host to a recursive domain name server. If the recursive domain name server caches the authoritative answer of the domain name query locally, then (2) directly returns the authoritative answer to the user; otherwise (3) the recursive domain na...
