If you wish to register a domain to ensure that no one else is going to take it, however, you haven't created the site for it yet, you can park it. That is a service that registrar companies provide if a domain name is not linked to any web or e mail hosting service. This way, you'll be able to protect a brand name, for example, and you'll own the domain in question although it won't load any content. If you wish, you can choose some default template that the registrar provides, such as For Sale or Under Construction, alternatively you can forward the domain name to an alternative web address. The second option is very useful in case you own a few domains, but you want each and every one of them to open the same website. As an illustration, you may 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 only and the traffic to the other ones will be redirected to it.
