If you'd like to register a domain name to ensure that no one else will take it, but you have not created the website for it yet, you can park it. That is a feature that registrar companies offer when a domain address is not linked to any web or e mail hosting service. By doing this, you'll be able to protect a brand name, for example, and you'll own the domain in question although it won't load any content. If you wish, you can pick some standard template that the registrar provides, such as For Sale or Under Construction, or you can direct the domain to a new web address. The second option is very useful in case you own a number of domain names, 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 address only and the traffic to the other ones will be redirected to it.
