If you wish to register a domain to make sure that no one else is going to take it, however, you have not created the website for it yet, you could park it. This is a service that registrar companies provide whenever a domain name is not linked to any web or e mail hosting service. In this way, you can protect a brand name, for example, and you'll own the domain in question although it will not load any content. If you want, you can choose some standard template that the registrar provides, like For Sale or Under Construction, alternatively you can forward the domain to an alternative web address. Your second option is extremely helpful if you own a few domain names, but you want each and every one of them to open the same website. For instance, you may register domain.net and domain.org, then park them and direct them to domain.com. In this example, you are going to need hosting for the third domain only and the traffic to the other ones will be redirected to it.
