If you'd like to register a domain name to ensure that nobody else is going to take it, however, you haven't developed the website for it yet, you may park it. That is a service that registrar companies offer if a domain address isn't linked to any web or e-mail hosting service. By doing this, you are able to protect a brand name, for example, and you'll own the domain address in question although it will not load any content. If you would like, you can pick some standard template that the registrar offers, such as For Sale or Under Construction, or you can forward the domain name to another web address. Your second option is very helpful in case you own a number of domain names, but you want every one of them to open the same site. For 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 name only and the traffic to the other ones is going to be redirected to it.
