Create a Domain Alias
Domain aliases make your website available from another domain name. For example, you can make www.example.net and www.example.org show content from www.example.com.
Navigate to the Aliases section in cPanel.
Type in the domain name you wish to make an alias.
Click on “Add Domain”.
Note: Domains must be registered with a valid registrar and configured to point to your DNS servers before they can be used as an alias.
