If you want to register a domain to ensure that nobody else is going to take it, however, you have not created the site for it yet, you can park it. It's a service that registrar companies offer when a domain address is not linked to any web or e-mail hosting service. By doing this, you'll be able to protect a brand name, for example, and you'll own the domain name in question although it will not open any content. If you would like, you can choose some default template that the registrar provides, such as For Sale or Under Construction, or you can forward the domain to a different web address. Your second option is very helpful if you own a number of domains, but you want each and every one of them to open the same site. For instance, you can register domain.net and domain.org, then park them and direct them to domain.com. In this example, you'll need hosting for the third domain address only and the traffic to the other ones will be redirected to it.
