Domain name resolution system and domain name resolution method

Abstract

The invention provides a domain name resolution system and a domain name resolution method that are used for attaining an aim of making a domain name configuration file be rapidly effective. The domain name resolution system comprises a management module, a conversion module, a data center and a serve, wherein the management module is used for managing corresponding relations between domain names and IP addresses and storing the corresponding relations in the management module in a sorted manner, the conversion module is used for converting each corresponding relation into a configuration file that can be identified by a server and sending each configuration file to the data center, the data center is used for storing the configuration file, and the server is used for storing the configuration file stored in the data center in the server; when a domain name resolution request sent via a client end is received, a configuration file corresponding to a domain name requested via the client end is read from the server according to the domain name requested via the client end, an IP address corresponding to the domain name requested via the client end can be determined according to the configuration file, and an IP address corresponding to the domain name requested via the client end can be fed back to the client end.

Description

technical field [0001] The embodiment of the present invention relates to the field of database technology, and in particular to a domain name resolution system and a domain name resolution method. Background technique [0002] Domain Name System (DNS), a distributed database on the Internet that maps domain names and IP addresses to each other, enables users to access the Internet more conveniently, without having to remember the IP address numerical string that can be directly read by the machine . The process of finally obtaining the IP address corresponding to the host name through the host name is called domain name resolution (or host name resolution). [0003] At present, when the smart DNS system provides an IP to request a domain name from the smart DNS, the DNS will return the requested resolution record according to the specific resolution rules according to the requested IP's operator and geographical information. However, because the traffic of content distrib...

Problems solved by technology

However, most of the existing DNS configures the domain name in a configuration file. If the service is updated, all domain name configurations will be reloaded, and the reloading speed is slow

[0004] To sum up, in the prior art, the corresponding relationship between the domain name and the IP address is stored in a configuration file, so that when the configuration file changes, the reloading speed is slow, which leads to the slow speed when the configuration file of the domain name is changed. slower
