An addon domain allows you to host a completely separate website within your hosting account, while a parked domain simply redirects to the same website as your primary location. To remove either, follow these steps.
1. Log in to your cPanel account.
2. In the Domains section, click on the Domains icon.
3. Locate the addon domain and then click on the Manage.
4. Click on the Remove Domain button.
5. Click Yes, Remove This Domain to confirm.
You should see a success message notifying you that your Add-on or Parked domain has been completely removed.
