Parked domains are additional domains hosted on your account which display the same website as your primary domain; however, you can give the parked domain its own email boxes.
For example, if you own domain1.com and it is the primary domain of your cPanel account, you can set up domain2.com as a parked domain and it will load the content of domain1.com. When you visit domain2.com, you will notice that although the content of domain1.com is loading in the browser, the address bar will display http://domain2.com/.
Domains must be registered with a valid registrar before they can be parked. In addition, a domain will not be functional unless it is configured to point to the same name servers as your primary domain.
To add a parked domain to your account:
1. Log into cPanel.
2. In the Domains section, click the Parked Domains icon.
3. Under Create a New Parked Domain, enter the domain name you would like to park on top of your primary domain.
4. Click Add Domain.
You have just added a parked domain.
