If you want to register a domain to make sure that nobody else is going to take it, however, you haven't developed the web site for it yet, you could park it. It's a feature that registrar companies offer when a domain address isn't linked to any web or e mail hosting service. In this way, you can protect a brand name, for instance, and you'll own the domain in question although it will not open any content. If you wish, you can choose some default template that the registrar provides, such as For Sale or Under Construction, you can also forward the domain name to a new web address. The second option is very helpful in case you own a number of domains, but you want each and every one 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 will need hosting for the third domain name only and the traffic to the other ones will be redirected to it.
