If you wish to register a domain to ensure that nobody else is going to take it, but you have not developed the website for it yet, you may park it. This is a service that registrar companies offer whenever a domain address is not connected to any web or e mail hosting service. That way, you'll be able to protect a brand name, for instance, and you'll own the domain in question although it won't load any content. If you want, you can choose some default template that the registrar provides, such as For Sale or Under Construction, or you can forward the domain name to a different web address. The second option is very helpful in case you own a few domain names, but you want all of them to open the same website. For example, you may 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 only and the traffic to the other ones will be redirected to it.
