Addon domains allow you to control multiple domains from a single cPanel account. An addon domain links a new domain name to a subdirectory of your account’s home or public_html (document root) directory and then stores its files in that subdirectory.
Once an additional domain has been created, you will have the ability to create email addresses and FTP accounts based off of these new addresses.
