If you'd like to register a domain name to make certain that nobody else will take it, but you have not developed the web site for it yet, you can park it. This is a feature that registrar companies offer if a domain address isn't linked to any web or e-mail hosting service. This way, you'll be able to protect a brand name, for instance, and you will own the domain in question although it will not open any content. If you want, you can choose some default template that the registrar offers, such as For Sale or Under Construction, you can also direct the domain name to an alternative web address. Your second option is extremely helpful if you own a number of domains, but you want every one of them to open the same site. For instance, you may 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.
