If you wish to register a domain to make certain that nobody else will take it, but you haven't created the site for it yet, you can park it. This is a service that registrar companies offer whenever a domain name isn't connected to any web or email hosting service. In this way, you'll be able to protect a brand name, for instance, and you'll own the domain name in question even though it won't load any content. If you wish, you can select some default template that the registrar provides, such as For Sale or Under Construction, alternatively you can forward the domain to a different web address. The second option is very helpful if you own a number of domains, but you want every one 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're going to need hosting for the third domain only and the traffic to the other ones is going to be redirected to it.
