If you want to register a domain to make certain that no one else is going to take it, however, you haven't developed the web site for it yet, you may park it. This is a service that registrar companies provide whenever a domain is not connected to any web or e mail hosting service. That way, you can protect a brand name, for instance, and you will own the domain address in question although it won't load any content. If you wish, you can pick some standard template that the registrar offers, like For Sale or Under Construction, or you can forward the domain name to a new web address. The 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 could register domain.net and domain.org, then park them and direct them to domain.com. In this example, you are going to need hosting for the third domain name only and the traffic to the other ones is going to be redirected to it.
