Abstract

The invention discloses a domain name resolution method and a device. The method comprises the steps of configuring the address list of a hypertext transmission protocol domain name resolution server HTTPDNS capable of resolving domains to be resolved; determining the address of a target HTTPDNS from the said address; sending HTTP request having the domains to be resolved to the address of the target HTTPDNS to obtain the resolution result returned by the target HTTPDNS. The invention is advantageous in that domain resolution is conducted through the determined target HTTPDNS; based on the current safety mechanism of HTTPDNS, domain hijacking can be effectively prevented, and safety and efficiency of domain resolution can be increased.

Description

technical field

[0001] The present invention relates to the field of computer technology, in particular to a domain name resolution method and device. Background technique

[0002] A domain name is a set of address conversion system specially established for the convenience of memory. To access a server on the Internet, it must be realized through an IP address. Domain name resolution (Domain name resolution, DNS) is to convert a domain name into an IP address again. the process of. One domain name corresponds to one IP address, and one IP address can correspond to multiple domain names; therefore, multiple domain names can be resolved to one IP address at the same time. Domain name resolution needs to be done by a dedicated domain name resolution server (DNS).

[0003] Domain name resolution is usually used as a precursor to a network connection, resolving computer names that are easy for people to remember into network addresses suitable for computer processing. Almost a...
