WHAT IS AN ADDON DOMAIN AND HOW DOES IT WORK?
An addon domain is a fully functional domain that can be created from within your control panel. This addon domain is a new, unique website hosted in a new folder on your account so that you can host several domains from one control panel. You can give an addon domain email addresses, forwarders, and more in the same way as a primary (main) domain on the account.
When you create an Addon domain, 3 things happen:
a folder is created in the 'public_html' directory
a subdomain is created for the primary domain and attached to the new folder
the new domain name is associated with the subdomain
For example, if the primary domain was 'abc.com' and you assign the Addon Domain 456. com' to the folder '456, the following routes (URLs) would be true:
abc.com/456
456.abc.com
456.com
All three of these paths would access the same directory and show the same website. However, in concern to your website's viewers going to 456.com, there is no evidence that they are being routed through 456.abc.com and everything will function as normal.
This all happens automatically when an Addon domain is assigned to an account; there is no need for further action necessary other than loading content into the addon domain folder.
Additionally, for those still concerned with 456.abc.com being active, there is a method in which you can disable the 456.abc.com route from accessing the site without disturbing the 456.com route. This can be found in our knowledge base article: Restrict subdomain access to addon domains
