If you want to register a domain name to ensure that no one else is going to take it, however, you haven't developed the web site for it yet, you may park it. It's a feature that registrar companies offer if a domain name isn't connected to any web or e mail hosting service. In this way, you'll be able to protect a brand name, for example, and you'll own the domain name 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 very helpful if you own a number of domain names, but you want every one of them to open the same website. For example, you could 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 address only and the traffic to the other ones is going to be redirected to it.
