Embodiment Construction

[0034] The basic idea of ​​the present invention is to enhance the function of the domain name server in the existing system, so that it can obtain the customer type according to the source IPv6 address information contained in the domain name query message, and provide differentiated IP address resolution results, thereby serving different customers Or the terminal provides differentiated services.

[0035] Below at first illustrate the relevant modification and expansion of the present invention in the domain name server.

[0036] In an existing domain name server, a resource record usually includes five items: domain name (Domain_name), time to live (Time_to_live), category (Class), type (Type) and value (RDATA). In the domain name server of the present invention, a user type (User_type) item is added to the resource record. For resource records containing the same domain name, if the client types are different, the corresponding values ​​(that is, IP addresses) may also b...

Abstract

The invention discloses a domain name differentiation analyzing method and a domain name server. The domain name differentiation analyzing method comprises the steps of: receiving a domain name query message which comprises a domain name and client type information to be analyzed; analyzing the domain name query message to obtain the domain name and the client type; and inquiring a resource record comprising the domain name and the client type, and returning a domain name response message comprising an IP address in the resource record obtained by inquiring. Through the domain name differentiation analyzing method and the domain name server, a differentiated domain name analyzing service can be provided for clients of different client types.

Description

technical field [0001] The invention relates to the technical field of the Internet domain name system, in particular to a domain name differentiation analysis method and a domain name server. Background technique [0002] The Domain Name System (DNS) is a system that converts Internet (Internet) domain names into IP addresses. In the domain name system, the domain name server (DomainName Server) automatically converts the domain name of the URL to be accessed provided by the domain name client (Domain Name Client) into the corresponding IP address, and provides it to the domain name client. In this way, the domain name client computer can access the desired website according to the obtained IP address. [0003] figure 1 A schematic diagram showing a domain name resolution process in the prior art. like figure 1 As shown, first, the domain name client sends a domain name query message to the domain name server, and queries the domain name server "what is the IP address o...
