If you wish to register a domain name to make certain that nobody else is going to take it, but you haven't built the web site for it yet, you may park it. That is a service that registrar companies offer whenever a domain isn't connected to any web or email hosting service. In this way, you can protect a brand name, for example, and you'll own the domain address in question although it will not load any content. If you wish, you can choose some default template that the registrar offers, such as For Sale or Under Construction, alternatively you can direct the domain to a new web address. The second option is extremely helpful if you own a number of domain names, but you want every one of them to open the same website. As an illustration, you may register domain.net and domain.org, then park them and direct them to domain.com. In this example, you're going to need hosting for the third domain address only and the traffic to the other ones is going to be redirected to it.
