If you wish to register a domain to make sure that no one else will take it, but you have not developed the site for it yet, you may park it. This is a service that registrar companies offer when a domain name is not connected to any web or email hosting service. This way, you'll be able to protect a brand name, for instance, and you will own the domain name in question although it will not load any content. If you wish, you may choose some default template that the registrar provides, such as For Sale or Under Construction, you can also direct the domain to an alternative 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 example, you may 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 only and the traffic to the other ones will be redirected to it.
