Domain name analyzing method and server

Abstract

The invention discloses a domain name analyzing method and a server, and belongs to the technical field of Internet. The method comprises the following steps of receiving a domain name analyzing request which is sent by an application client via TCP (transmission control protocol) connection, wherein the domain name analyzing request carries a to-be-analyzed target domain name, and the designated server is an application server corresponding to the application client, or a preset confidential server, and is stored with a corresponding relationship between the domain name and an IP (internet protocol) address; according to the corresponding relationship between the domain name and the IP address, obtaining the target IP address corresponding to the target domain name, and sending the target IP address to the application client. The method has the advantages that because the designated server is the application server or the confidential server, the reliability is higher than the reliability of a DNS (domain name server); when the domain name analyzing request is processed by the designated server, the false analyzing of the domain name due to false IP address of the DNS configured by the system is avoided, and the accuracy of domain name analyzing is improved.

Description

technical field [0001] The invention relates to the technical field of the Internet, in particular to a domain name resolution method and server. Background technique [0002] Each terminal or server in the Internet has a unique IP (Internet Protocol, Internet Protocol) address to distinguish it from thousands of other terminals and servers in the Internet. Because the IP address is represented by binary numbers, it is difficult for users to remember and write when using it. In order to facilitate the user's memory, a symbolic address, namely the domain name, has been developed on the basis of the IP address. Each domain name corresponds to a specific IP address. In this way, the terminal can obtain the corresponding IP address based on the domain name, so as to obtain the corresponding service according to the obtained IP address. Wherein, the process that the terminal acquires the corresponding IP address based on the domain name is the process of domain name resolution...

Problems solved by technology

[0004] However, in the above-mentioned domain name resolution process, since the DNS server is a public server, the IP address of the DNS server is easily tampered with by operators, network service providers, etc. In this case, the IP address of the DNS server configured by the system It is likely to be wrong or untrustworthy. At this time, the application client sends a domain name resolution request to the DNS server corresponding to the IP address, and the incorrect IP address will be resolved, resulting in failure to obtain services normally.
