If you want to register a domain name to make certain that no one else will take it, however, you have not developed the site for it yet, you can park it. This is a feature that registrar companies offer if a domain name isn't linked 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 name in question even though it will not load any content. If you would like, 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. The second option is extremely helpful in case you own a few domains, but you want each and every one of them to open the same site. As an example, 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 only and the traffic to the other ones is going to be redirected to it.
