Parked domains are additional domains hosted on your account which display the same website as your primary domain and share web statistics as well. Parked domains are often used by businesses that want to have more than one web address for advertising purposes.
A parked domain is a domain name pointed to one of our web servers and each one you setup in your Control Panel, will point to your homepage of your primary web hosting account. Parked domains have no other functionality.
So if the domain of your web hosting account is www.abc.com and you park a new domain in your control panel; say www.xyz.com, www.xyz.com would point to the same homepage of your primary hosting account which is www.abc.com.
