How to Create a Domain Alias in cPanel
This demo assumes you've already logged into cPanel and are starting on the home screen.
Now, let's learn how to create a domain alias.
Click the "Aliases" icon. A domain alias is useful when you have additional domain names that you want people to be able to use to get to your website. Enter the new domain, then click "Add Domain".
That's it. Now, when someone browses to "mybiz123.info", they'll automatically be redirected to "mybiz1234.com". Be sure to set your Domain Alias's DNS settings to the same as your main domain so the redirection will work properly.
This is the end of the tutorial. You now know how to create a domain alias from cPanel.
