What does the domain name mean?

Domain name, referred to as domain name or domain for short, is the name of a computer or computer group on the Internet. It consists of a series of names separated by dots and is used to identify the electronic position (sometimes called geographical position) of the computer during data transmission.

Domain name system is the core service of Internet. As a distributed database that can map domain names and IP addresses, it can make people access the Internet more conveniently, without having to remember the number of IP addresses that the machine can directly read.

Any computer network using IP can use DNS to realize its own private name system. However, the term "domain name" is most commonly used when it refers to a domain name implemented on a public Internet DNS system.
