A website domain name is the name of a computer or computer group on the Internet consisting of a string of dot-separated names. It is used to locate the computer during data transmission. Domain names are composed of two basic types: domains named after the nature of the organization and domains named after the country code.

What is a website domain name?

A domain name (English: Domain Name), also known as a domain, is a computer or computer on the Internet consisting of a string of names separated by dots. The name of the group used to identify the location (sometimes geographical location) of the computer during data transfer.

Because IP addresses are inconvenient to remember and cannot display the name and nature of the address organization, people have designed domain names and combined domain names and IP addresses through the Domain Name System (DNS, Domain Name System). Mutual mapping makes it easier for people to access the Internet without having to remember a string of IP addresses that can be directly read by machines.

Although the IP address can uniquely mark a computer on the network, the IP address is a long string of numbers, which is not intuitive and very inconvenient for users to remember, so people invented another character-based address scheme. , the so-called domain name address. There is a one-to-one correspondence between IP addresses and domain names. This domain name address information is stored in a host called a domain name server (DNS). Users only need to know the easy-to-remember domain name address, and the corresponding conversion work is left to Given to the domain name server. A domain name server is a server that provides conversion services between IP addresses and domain names.

Domain name network access structure:

Host name, organization name, network name, top-level domain name

This is a hierarchical management model. The domain name is expressed in words rather than in words. Numerical IP addresses are easy to remember. Networks at all levels that join the Internet name computers within the network in accordance with the naming rules of the domain name server, and are responsible for completing the conversion of domain names to IP addresses during communication. The Defense Data Network Communications Center (DINNIO), part of the U.S. Department of Defense, is responsible for the registration and management of the highest-level domain names on the Internet. It is also responsible for the allocation of IP addresses. Domain names are composed of two basic types: domains named after the nature of the organization and domains named after the country code. Common domain names named after the nature of the organization generally consist of three characters.
