If you'd like to register a domain to make certain that nobody else is going to take it, but you haven't created the site for it yet, you may park it. It's a service that registrar companies offer if a domain is not connected 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 won't load any content. If you'd like, you may choose some default template that the registrar provides, such as For Sale or Under Construction, or you can direct the domain to a different web address. The second option is very useful if you own a few domain names, but you want all of them to open the same site. For example, you may 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 is going to be redirected to it.
