If you want to set up a domain that will only be used to point to your primary (main) domain, then you can create the domain as a Parked Domain. For example, if we wanted to have all traffic that went to whhsupport.net directed to whhsupport.com, we would add whhsupport.net as a Parked Domain.
To add a Parked Domain, first select "Parked Domain" under the "Domains" sub-header in your cPanel:
On this screen, simply put the domain you want to add in the box and click on "Add Domain:"
Once it has been added, you can verify it on the Parked Domain screen:
Please note, removing a domain from cPanel does not cancel the registration of that domain, these are separate steps. If you have a domain you do not wish to renew, please see our article on how to cancel a domain registration.
