If you wish to register a domain name to ensure that no one else is going to take it, however, you haven't created the web site for it yet, you could park it. This is a service that registrar companies provide when a domain address 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 address in question although it won't open any content. If you wish, you may choose some standard template that the registrar provides, such as For Sale or Under Construction, or you can forward the domain to a different web address. The second option is very helpful in case you own a number of domain names, but you want every one of them to open the same site. As an illustration, you can register domain.net and domain.org, then park them and forward them to domain.com. In this example, you are going to need hosting for the third domain name only and the traffic to the other ones is going to be redirected to it.
