If you'd like to register a domain to make sure that nobody else will take it, but you haven't created the website for it yet, you can park it. That is a service that registrar companies provide if a domain is not connected to any web or e-mail hosting service. This way, you are able to protect a brand name, for example, and you'll own the domain address in question although it will not load any content. If you would like, you may choose some standard template that the registrar provides, such as For Sale or Under Construction, you can also forward the domain name to another 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 can 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 address only and the traffic to the other ones is going to be redirected to it.
