What is the Difference Between a Parked and Addon Domain
From Free Hosting Wiki
When you add a domain in cPanel, you have two options: Parked or Addon.
- A parked domain will show the exact same site as your main domain. It loads the files from the public_html folder. However, the email accounts are separate from your main domain unless you added the email account as a wild card email. Parked domains can also be redirected, so that a user that visits the parked domain is redirected to the main domain.
- A addon domain allows you to run a separate site. It loads the files from a descendent folder of your public_html folder. You can pick public_html as the site root, in which case an addon domain will show the same site as your main domain.
