A domain name (often simply called a domain) is an easy-to-remember name that’s associated with a physical IP address on the Internet. It’s the unique name that appears after the @ sign in email addresses, and after www. in web addresses. For instance, the domain name example.com might translate to the physical address 198.102.434.8. Other examples of domain names are google.com and wikipedia.org. Using a domain name to identify a location on the Internet rather than the numeric IP address makes it much easier to remember and type web addresses. Anyone can purchase a domain name. You just go to a domain host or registrar, find a name no one else is using, and pay a small annual fee to own it.
