Essentially, to park a domain name means to reserve your registered domain until you have created the site content, found a hosting provider, or sold the domain to a third party. When you park your site, a temporary Web page will be displayed until you have decided what to do with the domain. Registrants who do not yet have a hosting provider often use domain name parking.
Parking options include a one-page Web site that will inform the visitor to the site that, for example, this page is “Under Construction,” “Coming Soon,” or “For Sale.” You can also elect to have a customized page displayed.

Also when parking a domain, the parked domain shows the website of the domain it is parked at. It is like adding a po box to your house address. Website Designs
