Hello dear, happy to answer your questions <>

A domain name, also known as a domain name, is the name of a computer or group of computers on the Internet composed of a string of names separated by dots, which is used to locate and identify the computer (sometimes referring to geographical location) during data transmission. Due to the shortcomings of IP addresses, which are inconvenient to remember and cannot display the name and nature of the address organization, people have designed domain names and mapped domain names and IP addresses to each other through the domain name system (DNS), so that people can more easily access the Internet Raid Network without having to remember the number of IP addresses that can be read directly by machines.
