DNS is like a phone book for the server. If you know a person’s name but don’t know telephone number, you can simply search it in a phone book. Domain Name Server provides this same service to the Internet. When it comes to talking on the Internet, computers don’t recognize each other by name. They prefer numbers, usually.

It happens on a name server that holds a directory to transfer the name to number. The name server for this purpose is part of the Domain Name System, a distributed system that exists across the planet. It is one of the most important elements of the Internet as we know it now. Without DNS, we would certainly have to know all those numbers; it will be like trying to remember thousands of phone numbers just to search the web and emails.

But it has to initial check in at a resolving Domain Name Server to see what the actual address is. The resolver could be at your Internet Service Provider, which makes it quick. But if it doesn’t know, the resolver will send the appeal to a root server that is part of the DNS.
