If you wish to register a domain name to make sure that no one else will take it, but you haven't built the website for it yet, you may park it. This is a feature that registrar companies provide when a domain address isn't linked to any web or e mail hosting service. In this way, you can protect a brand name, for instance, and you will own the domain name in question although it won't load any content. If you'd like, you can pick some default template that the registrar provides, like For Sale or Under Construction, alternatively you can direct the domain name to another 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 website. As an example, you can register domain.net and domain.org, then park them and direct them to domain.com. In this example, you are going to need hosting for the third domain address only and the traffic to the other ones is going to be redirected to it.
