What is a parked domain?
Parked domains are secondary domains that you point to your account. They will display the same content as your primary domain, and otherwise function as an exact copy of the primary domain. Parked domains are often used by businesses that want to have more than one web address for advertising purposes. Do not confuse this with domain parking offered by domain registrars. When a domain registrar offers such a service they mean to park your domain on their servers, not point it to your webhosting account.
