A domain name, or URL, is the name of your website. More specifically:
- A Domain Name (yourname.com) is an Alias (text name) corresponding to the numeric IP address of your website on the Internet.
- Humans are better at remembering and relating to text names. Computers like numbers. To bridge this digital divide Registrars maintain a massive database of which Domain Names belong to what IP addresses.
- You pay your Registrar an annual fee for this translation service, as it is an ongoing service; every-time someone types in your domain name you Registrar must tell their computer which IP address they should go to.
