Problems solved by technology

[0009] (2) Intelligent analysis is not accurate
The key to this solution is that the authoritative DNS must be able to accurately identify user information through the egress IP of the Local DNS, but in fact this heavily depends on the specific deployment of the operator's Local DNS
[0011] (3) Analysis changes take effect slowly
In addition, in order to save traffic settlement fees, some operators forcibly extend the validity period of the cache even for several hours.
Obviously, this will lead to a serious drop in the sensitivity of the service provider's global traffic scheduling based on DNS resolution. In the disaster recovery switchover scenario based on DNS resolution, it will also cause the corresponding users to be unavailable for a long time

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...
