This article mainly introduces the use of caching in the domain name server, which has a certain reference value. Interested friends can refer to it. I hope you will gain a lot after reading this article. Let's take a look at it.

The role of caching in the domain name server: the recently visited URL information is stored in the cache and will be read from the cache when it is accessed again without the need for re-parsing. This can speed up the response speed of the domain name service.

DNS (Domain Name Server, domain name server) is a server that translates domain names (domain name) and corresponding IP addresses (IP address). A table of domain names (domain name) and corresponding IP addresses (IP address) is saved in DNS to resolve the domain name of the message. A domain name is the name of a computer or computer group on Internet that is used to identify the electronic (and sometimes geographical) location of the computer during data transmission. A domain name consists of a string of names separated by dots, which usually contains the name of the organization, and always includes a two-to three-letter suffix to indicate the type of organization or the country or region in which the domain is located.

It's the same as your browser cache. The source pages you have viewed will be stored in the cache. When browsing again, some of the content in the web page is read from the cache, so it is very fast. The same is true of the cache of the domain name server. The URL information you have visited recently is stored in the cache and will be read from the cache when you visit it again. There is no need to reparse it. This speeds up the response speed of the domain name service.
