How do domains work?

When visitors enter your domain name into a Web browser, the browser request uses your domain name to find the domain name’s associated IP address and, therefore, the website. People use domain names instead of IP addresses because it is easier to remember a name rather than a series of numbers.

Your domain name and its associated IP address are stored in a common database along with every other domain and associated IP address that are accessible via the Internet.

What is the ‘www’ before my domain name?
The www before your domain name is a subdomain, not part of the domain name itself. Therefore, if you set up your www CNAME record to point to your primary A record, your site will resolve both at www.coolexample.com and coolexample.com.

If you can reach your website by typing in your domain without the www but cannot reach it when you type the www, then your CNAME might be set up incorrectly. Follow the instructions below to ensure your domain name’s settings are correct.

What is a URL?

A URL, or Uniform Resource Locator, is the address of an Internet website or webpage. Think of a URL as a street address for the location of information on the Internet. For instance, a complete URL like http://coolexample.com/music, points you to the music page of the coolexample.com website.

Take a look at the anatomy of this URL to better understand how they direct online users to specific information: http://coolexample.com/funky/music.html
