Most of the plans allow for the adding of one or more "ADDON" Domains.
READ THIS BEFORE SETTING UP AN ADDON DOMAIN!
Make sure that you update the nameservers for your addon domain at your registrar with the same nameservers as used for your main domain (this is in your welcome e-mail). You cannot create an addon domain if your dns hasn't propagated to the server already. You will need to wait 24-48 hours before attempting to create your addon domain. Do not use 'www' in the addon domain name!
What is an addon domain?
An addon domain is a fully functional top level domain(TLD) that is pointed to a subdomain. With the Addon domain feature in cPanel you can create a separate domain next to your main domain in your account. The HTML contents of a subdomain goes into a subfolder in your /public_html/ folder of your account.
So if you were to add a domain named auto.com and your main domain is car.com, cPanel actually creates a subdomain called auto.car.com and this is transparent to you. Meaning that you do not actually see this fact. The contents which goes in the /public_html/auto/ directory will be visible via your browser under: auto.car.com AND more importantly directly at auto.com.
You can create POP mail accounts with auto.com and also the FTP can be accessed with auto.com (user for FTP should be auto@car.com). We actually suggest that you name the directories via cPanel for addon domains with the extention i.e. in the above example this would be /public_html/auto.com/ This will differentiate a simple sub-domain that you may add from an addon domain.
