Domain name resolution method, apparatus, device and computer storage medium

Abstract

The present invention provides a domain name resolution method, device, device, and computer storage medium, wherein the method includes: obtaining a domain name to be resolved and resolution requirement information; sending a domain name resolution request including the domain name and resolution requirement information to a domain name server; Receiving a resolution result for the domain name returned by the domain name server, where the resolution result includes an IP address that meets the resolution requirement information. The present invention carries resolution requirement information in the domain name resolution request, so that the domain name server can return an IP address that meets the resolution requirement information for the domain name according to the resolution requirement information, thereby satisfying the personalized resolution requirement of the terminal device.

Description

【Technical field】 [0001] The invention relates to the technical field of network communication, in particular to a domain name resolution method, device, equipment and computer storage medium. 【Background technique】 [0002] Domain name resolution is to point domain names to IP addresses in cyberspace, so that people can easily access sites (service devices that provide services or resources) through simple network domain names. An IP address is a numerical address that identifies a site on the network. For the convenience of memory, a domain name is used instead of an IP address to identify the address of the site server. Domain name resolution is the conversion process from domain name to IP address, which is completed by DNS server. Such as figure 1 As shown in , when a terminal device wants to access a certain site, it sends a domain name resolution request containing the domain name of the site to be accessed to the DNS server, and the DNS server performs domain name ...

Problems solved by technology

[0003] However, with the gradual expansion of the scale of the Internet, the number of devices on the Internet is increasing, and there are often many site servers under the same domain name that can provide services for terminal devices. For disasters and other purposes, these site servers are usually distributed in different regions, connected to different network operators, and have different network bandwidth and network processing capabilities. At the same time, network links and structures on the Internet are becoming more and more complex

The existing method of domain name resolution only requires the DNS server to return one of the IP addresses corresponding to the domain name according to the domain name, which is often difficult to meet the individual needs of the terminal device.

For example, if the link corresponding to the IP address returned by the DNS server for a certain domain name is interrupted, the DNS server does not know that when the terminal device requests domain name resolution again, it wishes to exclude the IP address, then the existing method cannot be implemented
