If you want to register a domain name to make sure that nobody else is going to take it, however, you haven't developed the website for it yet, you may park it. This is a feature that registrar companies offer whenever a domain isn't connected to any web or e-mail hosting service. That way, you are able to protect a brand name, for example, and you'll own the domain in question even though it won't open any content. If you want, you can select some standard template that the registrar provides, such as For Sale or Under Construction, alternatively you can direct the domain to a different web address. The second option is extremely helpful in case you own a number of domains, but you want all of them to open the same website. For instance, you can 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 will be redirected to it.
