About domain names

A domain name is an address on the internet.

The two uses of domain names people will be most familiar with are website addresses  – e.g. www.auda.org.au,  and email addresses, where the domain name follows the ‘@’ symbol e.g. [email protected]

Computers find websites by searching not for domain names, but for a long and unique set of numbers associated with every domain name. These numbers are called IP addresses. An example of an IP address is 192.160.1.50

The system used to seamlessly match domains and IP addresses is called the Domain Name System or DNS.
