Embodiment Construction

[0023] In the prior art, a domain name is the name of a certain computer or computer group on the Internet, and is used to identify the computer's electronic location (or sometimes geographical location) during data transmission. A domain name is a series of dot-separated names, usually containing the name of an organization, and always includes a two- or three-letter suffix to indicate the type of organization or the country or region in which the domain is located. Such as figure 1 As shown, the domain name has a tree structure, and it is divided into multiple levels from the root domain name to the DNS server directly served. For example, "www.pku.edu.cn" is a domain name, which is divided into 4 levels, which are host The name "www", the third-level domain name "pku", the second-level domain name "edu", and the top-level domain name "cn". It also assigns a unique IP address to each host on the Internet. Additionally, it is also possible to figure 1 The DNS tree structur...

Abstract

The embodiment of the invention provides a distributed domain name analysis method and device. The method comprises the following steps: a domain name analysis server receives a domain name analysis request sent by a client side; if the domain name analysis server does not exist an IP address corresponding to a domain name locally, the domain name analysis request is sent to other domain name analysis servers in a peer-to-peer networking; and the domain name analysis server receives the IP address which is corresponding to the domain name and is sent by the other domain name analysis servers, and sends the IP address to the client side. According to the distributed domain name analysis method and device provided by the embodiment of the invention, when the IP address corresponding to a to-be-analyzed domain name does not exist locally, the domain name analysis request is sent to the other domain name analysis servers in the peer-to-peer networking so as to query the IP address corresponding to the to-be-analyzed domain name from the other domain name analysis servers; because the domain name analysis servers in the peer-to-peer networking are in peer-to-peer, each of the domain name analysis servers is dynamically synchronous; and therefore, the problem of network paralysis due to a fact that an institution of a root domain or a top-level domain stops a service is avoided.

Description

technical field [0001] The embodiments of the present invention relate to the field of communication technologies, and in particular, to a distributed domain name resolution method and device. Background technique [0002] A domain name server (Domain Name Server, DNS) is a server that converts a domain name (domain name) and its corresponding IP address (IP address). A table of domain names and corresponding IP addresses is stored in the DNS. After receiving the domain name request sent by the client, the DNS queries the table corresponding to the domain name and the IP address to obtain the table corresponding to the domain name. The IP address corresponding to the domain name in the domain name request, and returns the IP address to the client. [0003] Usually the general structure of the Internet host domain name is: host name. third-level domain name. second-level domain name. top-level domain name. The top-level domain name of the Internet is registered and managed ...
