If you want to register a domain name to make sure that nobody else is going to take it, but you haven't built the website for it yet, you can park it. That is a feature that registrar companies offer if a domain address isn't linked 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 name in question even though it won't load any content. If you wish, you can select some default template that the registrar offers, such as For Sale or Under Construction, you can also direct the domain name to a new web address. The second option is very helpful if you own a number of domain names, but you want each and 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'll need hosting for the third domain address only and the traffic to the other ones is going to be redirected to it.
