Domain aliases make your website available from another domain name. For example, you can make www.example.com and www.example.net show content from www.example.org. 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.
1. Login to cPanel to accomplish this task.
2. Navigate to “Domains” section of the cPanel and click on “Aliases“.
3. Enter the domain name that you want to be an alias and click on the button “Add Domain”.
You can always come back to this page to manage aliases.
