Why are domain names used?


There are millions of unique websites and each website resides on a web server. Each web server can be identified by a unique address known as IP Address. In order to find the web server for a particular website, one has to remember the IP address of that server. IP addresses consist of digits only (e.g. 209.170.32.50) and are difficult to remember. Therefore, domain names were introduced in 1985 to create an easy-to-remember mapping of the server address and the web server location, where the actual website pages reside.
