If you'd like to register a domain to make sure that nobody else will take it, however, you haven't created the web site for it yet, you may park it. That is a feature that registrar companies offer when a domain name is not linked to any web or e mail hosting service. In this way, you are able to protect a brand name, for instance, and you will own the domain address in question even though it will not load any content. If you'd like, you can pick some default template that the registrar offers, such as For Sale or Under Construction, or you can forward the domain to a different web address. The second option is very helpful if you own a few domain names, but you want all of them to open the same site. For instance, you could register domain.net and domain.org, then park them and forward them to domain.com. In this example, you're going to need hosting for the third domain name only and the traffic to the other ones is going to be redirected to it.
