If you want to register a domain to make sure that no one else will take it, but you haven't developed the site for it yet, you can park it. It's a service that registrar companies offer whenever a domain address isn't connected to any web or email hosting service. By doing this, you'll be able to protect a brand name, for instance, and you will own the domain in question even though it won't load any content. If you wish, you can pick some default template that the registrar provides, like For Sale or Under Construction, alternatively you can forward the domain name to a different web address. The second option is very helpful if you own a few domains, but you want every one of them to open the same website. As an example, you could 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 name only and the traffic to the other ones is going to be redirected to it.
