What does it mean to Park my domain

Domain parking refers to the registration of a domain that does not currently have any designated DNS information to point to a website or email service. The DNS information for all new domain registration with Rebel will be defaulted to park on our nameservers, unless otherwise specified in the Portfolio Defaults. A parked domain will show one of our parking pages. It allows the community to know that the domain is registered and active, but simply does not have a website accompanying it.
