What is a domain name?
A domain name is a textual version of an IP Address – the number that points to a particular website. For example, the number 184.108.40.206 is the IP Address for yahoo.com. Each domain name on the Internet corresponds to such numbers.
Without domain names, each and every website would have to be recalled by a number like this, similar to the telephone system, but much more difficult to remember. For this reason, domain names were introduced, and have made navigation on the internet much simpler.
A domain name is a unique address that can be used on the internet. It’s what you see in the address bar after the World Wide Web (WWW) in your web browser and it’s what comes after the at (@) sign in an email address.
The domain name service is basically a large database which stores on various computers all domain names which are active on the internet.
