Problems solved by technology

Either way, it will affect the business requests of the APP itself, and various security issues will be derived in case of malicious attacks
[0004] For the scenario where the service center is deployed in multiple computer rooms, when the service center needs to be switched, the DNS cache will cause delays and affect the timeliness of business requests
And when initiating access services across operator networks, there will also be problems with poor network performance or unavailability

Abstract

The present invention provides a domain name resolution method and device. The method comprises the following steps: determining a domain name to be accessed; obtaining a mapping relationship betweena local domain name and a network address; determining, according to the domain name to be accessed and the mapping relationship, a target address to be accessed; and initiating an access request based on the target address. The technical scheme of the invention can avoid the problem of DNS hijacking, can reduce the delay of the network request and effectively improves the network performance.

Description

technical field [0001] The present invention relates to the technical field of the Internet, in particular to a domain name resolution method and device. Background technique [0002] The first step of an APP (Application, application program) client sending an access request requires DNS (Domain Name System, Domain Name System) resolution. Due to the existence of cache (high-speed buffer memory), most of the resolution requests will not generate relatively large big delay. At present, each terminal manufacturer has its own cache expiration policy. For example, for the IOS system, the DNS cache generally expires after 24 hours. At the same time, when the terminal enters the flight mode and then exits, powers on and off, and resets network settings, etc., it will also cause Clearing of DNS cache. Therefore, when the user opens the APP again after a long period of time, it usually goes through a complete DNS resolution process. When the network condition is poor, the total t...
