If you wish to register a domain name to make sure that no one else is going to take it, however, you have not developed the website for it yet, you may park it. This is a feature that registrar companies offer if a domain isn't linked to any web or email hosting service. By doing this, you'll be able to protect a brand name, for instance, and you'll own the domain name in question even though it won't load any content. If you want, you may choose some standard template that the registrar provides, such as For Sale or Under Construction, you can also forward 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 site. For instance, 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 only and the traffic to the other ones is going to be redirected to it.
