A domain name is your identity on the net. So that we can find it on the Internet, the net has built a system of numerical addresses called Internet Protocol (IP-addresses). Based on these IP-addresses, a system has been made with domain names, so that it is easier to remember and to make it possible to a have personal identity on the net.
Here is an example: active24.com has IP-address 220.127.116.11
A domain name is established as a alias for the IP address, so that you avoid to type in a sequence of numbers: Domain name as the IP-address 18.104.22.168: www.active24.com
