An additional domain or 'Addon Domain' is a separate domain that you can create/add to your web hosting package. The addon domain is not linked to the main domain or other domains that are on the same hosting package. Domains just share the same cPanel, web space, total resources within the hosting package.
It is possible to create separate e-mail addresses for each addon domain, unrelated to other domains that are on the same hosting package.
When creating an addon domain in cPanel, an addon domain folder will be automatically created.
Of course, when creating an addon domain, you can change the directory path if necessary, set a different name or a different path.
Within cPanel, click on the Add Domains icon
After that, fill in the required fields and click on ADD DOMAIN
