DNS (Domain Name Server, domain name server) is the domain name (domain name) and the corresponding IP address (IP address) converted server. DNS stores a table of domain names and corresponding IP addresses to resolve the domain names of messages.

A domain name is the name of a computer or computer group on the Internet. It is used to identify the electronic location (sometimes also the geographical location) of the computer during data transmission. A domain name is a string of dot-separated names, usually including the name of an organization, and always includes a two- or three-letter suffix to indicate the type of organization or the country in which the domain is located.

Overview

The software that translates domain names into IP addresses is called the Domain Name System, or DNS. It is a way of managing names. This method is to divide different groups into responsible for the names of each subsystem. Each layer in the system is called a domain, and each domain is separated by a dot. The so-called domain name server (Domain Name Server, Name Server for short) is actually a host equipped with a domain name system. It is a hierarchical database capable of name resolution.
