# What is an addon domain?

An addon domain is a fully working domain that you may set up from your control
panel. This addon domain is a new, distinct website housed in a new subdirectory
on your account, allowing you to host several domains from a single control
panel. You may provide email addresses, forwarders, and other services to an
addon domain in the same manner that you can to a principal (main) domain on the
account.







When you create an Addon domain, 3 things happen:

 1. A folder is created in the ‘public_html‘ directory

 2. A subdomain is created for the primary domain and attached to the new folder

 3. The new domain name is associated with the subdomain



For example, if the primary domain was ‘abc.com [http://abc.com]‘ and you assign
the Addon Domain' 123.com [http://123.com]‘ to the folder ‘123', the following
routes (URLs) would be true:

 * abc.com/123 [http://abc.com/123]

 * 123.abc.com [http://123.abc.com]

 * 123.com [http://123.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 123.com
[http://123.com], there is no evidence that they are being routed through
123.abc.com [http://123.abc.com], and everything will function as normal.
