A Parked Domain is an inactive domain reserved for later use or one that points to another existing domain.
For example, the domain name for your hosting account is "domain.com" and you also have registered "domain.net" through your domain.com Domain Manager. You may point domain.net to the domain.com IP address. Internet
users can now access your Web site using either domain name.
