If you want to register a domain name to make sure that nobody else is going to take it, but you have not developed the web site for it yet, you can park it. It's a feature that registrar companies offer whenever a domain address isn't connected to any web or e mail hosting service. This way, you are able to protect a brand name, for example, and you'll own the domain in question although it won't open any content. If you want, you can choose some standard template that the registrar provides, like For Sale or Under Construction, you can also direct the domain to an alternative web address. The 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 can register domain.net and domain.org, then park them and direct them to domain.com. In this example, you will need hosting for the third domain name only and the traffic to the other ones will be redirected to it.
