If you'd like to register a domain to ensure that no one else is going to take it, however, you have not created the web site for it yet, you may park it. That is a feature that registrar companies offer whenever a domain name isn't linked to any web or e-mail hosting service. This way, you can protect a brand name, for example, and you'll own the domain address in question even though it will not open any content. If you wish, you can pick some standard template that the registrar provides, like For Sale or Under Construction, or you can direct the domain name to an alternative web address. The second option is extremely helpful in case you own a number of domain names, 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 is going to be redirected to it.
