If you wish to register a domain name to ensure that no one else will take it, but you haven't created the website for it yet, you can park it. This is a service that registrar companies offer if a domain is not linked to any web or email hosting service. In this way, you'll be able to protect a brand name, for example, and you'll own the domain name in question even though it won't open any content. If you'd like, you may choose some standard template that the registrar offers, such as For Sale or Under Construction, or you can forward the domain to a different web address. Your second option is very helpful in case you own a few domain names, but you want every one of them to open the same site. As an illustration, you can register domain.net and domain.org, then park them and forward them to domain.com. In this example, you'll need hosting for the third domain address only and the traffic to the other ones is going to be redirected to it.
