If you'd like to register a domain to make certain that no one else will take it, however, you have not developed the site for it yet, you may park it. It's a service that registrar companies provide whenever a domain isn't connected to any web or e-mail hosting service. By doing this, you'll be able to protect a brand name, for example, and you will own the domain name in question although it won't open any content. If you'd like, you can choose some standard template that the registrar offers, like For Sale or Under Construction, or you can forward the domain to a different web address. Your second option is extremely helpful if you own a few domains, but you want all of them to open the same site. As an illustration, you can register domain.net and domain.org, then park them and forward them to domain.com. In this example, you'll need hosting for the third domain only and the traffic to the other ones will be redirected to it.
