How domain name work?
If we type the domain name in the browser it directly goes to the Domain Service Provider and Domain Service Provider is connected with Domain registry. For every domain extension like .com, .in, .ga there is a separate registry maintained globally. The Domain Service Provider finds the equivalent IP address for the given domain and sends your request to the respective server. The server has a static IP address. So the server can accept the request provide the response for your request(your IP Address) correctly(Technical point of view – your IP address asks for some data as a request to Server IP address and the Server IP provide the requested data as a response).
Users of the domain name
A domain name is used for finding and identifying computers on the Internet. Computers use IP addresses, which are a series of numbers. However, it is difficult for humans to remember strings of numbers. Because of this, domain names were developed and used to identify entities on the Internet rather than using IP addresses.
