Problems solved by technology

[0003] In view of the above-mentioned shortcomings of the prior art, the purpose of the present invention is to provide a method and system for domain name resolution, which is used to solve the problem that the hosting server needs to load multiple configurations of the source server in the prior art, resulting in long time-consuming and high system operating pressure problem, and the existing hosting server cannot obtain the optimal feedback information according to the IP information of the requesting server, and cannot find the corresponding information records in the cache module or cache the parsed information according to the IP information of the requesting server, etc. The resulting operation is not flexible enough, etc.

Abstract

The present invention provides a domain name resolution method and system. The method is applied to a managed server. The managed server is configured with a source server IP of a source server. The method comprises: receiving a piece of request information sent by a request server according to a preset managed server IP corresponding to a domain name; the request information comprising a request server IP; inquiring whether an information record corresponding to the request information exists in a caching module or not; if so, returning the information record to the request server; if not, forwarding the request information to the source server corresponding to the source server IP and receiving feedback information, sent by the source server, corresponding to the request information so as to store the request information in the caching module as a new information record; and sending the feedback information to the request server. The present invention can quickly, flexibly and conveniently respond to a domain name resolution request.

Description

technical field [0001] The invention relates to the field of domain name resolution, in particular to a domain name resolution method and system. Background technique [0002] DNS is an open system that provides UDP (User Datagram Protocol, User Datagram Protocol) connectionless services, and is vulnerable to DDOS attacks. When the attack cannot withstand the attack, it is necessary to quickly transfer the domain name to a new server. Existing domain name hosting usually authorizes the hosting server to load the configuration of the source server. When a requesting server makes a request for the IP of the corresponding domain name, it obtains the corresponding resolution information from the hosting server. The existing domain name hosting In the system, the requesting server only communicates with the hosting server, and the hosting server needs to load the configuration of the source server, which takes a long time and increases the pressure on the system operation, and th...
