Definitions for "Parked Domain"
A domain which is owned by someone, but does not point at an IP. Domains are parked to "put a hold" on a domain, especially if the registered owner of the domain does not have a site but doesn't want the domain to be used by anyone else (a trademark issue, a person's name, et cetera). Many places, including Scribehost, will park domains for no charge.
