This article introduces the knowledge of "what exactly is a DNS server". Many people will encounter such a dilemma in the operation of actual cases, so let the editor lead you to learn how to deal with these situations. I hope you can read it carefully and be able to achieve something!

Generally speaking, DNS is the abbreviation of computer Domain name system (Domain Name System). It is composed of a parser and a domain name server. A domain name server is a server that stores the domain names and corresponding IP addresses of all hosts in the network, and has the function of converting domain names into IP addresses. The domain name must correspond to an IP address, and an IP address can correspond to multiple domain names at the same time, but the IP address does not necessarily have a domain name.

Generally speaking, the domain name system adopts a hierarchical structure similar to the directory tree, and the domain name server is the server side in the client / server mode, which has two main forms: the main server and the forwarding server. The process of mapping a domain name to an IP address is called domain name resolution. On Internet, the domain name and IP address are one-to-one (or many-to-one). Although the domain name is easy for people to remember, the machines can only know the IP address each other. The translation between them is called domain name resolution. Domain name resolution needs to be done by a special domain name resolution server. DNS is the server for domain name resolution.

DNS naming is used in TCP/IP networks such as Internet to find computers and services through user-friendly names. When a user enters a DNS name in the application, the DNS service can resolve the name to other information related to it, such as the IP address. Because, when you are on the Internet, the URL you enter is to find the corresponding IP address through the domain name resolution system, so that you can surf the Internet. In fact, the ultimate point of the domain name is IP.

In short, the DNS server is a domain name system or domain name service, which assigns domain name addresses and IP addresses to hosts on the Internet. If the user uses the domain name address, the system will automatically change the domain name address to the IP address. The domain name service is an Internet tool that runs the domain name system. The server that executes the domain name service is called the DNS server. It answers the query of the domain name service through the DNS server.
