If you'd like to register a domain to make sure that no one else will take it, but you haven't developed the web site for it yet, you may park it. It's a service that registrar companies provide whenever a domain address isn't connected to any web or e mail hosting service. That way, you are able to 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 select some default template that the registrar provides, like For Sale or Under Construction, or you can direct the domain to a different web address. The second option is very helpful if you own a few domain names, but you want each and every one of them to open the same website. As an illustration, you can register domain.net and domain.org, then park them and forward them to domain.com. In this example, you will need hosting for the third domain address only and the traffic to the other ones is going to be redirected to it.
