If you want to register a domain to ensure that no one else is going to take it, but you haven't created the web site for it yet, you could park it. It's a service that registrar companies offer when a domain address is not linked to any web or e mail hosting service. In this way, you are able to protect a brand name, for example, and you'll own the domain address in question even though it won't load any content. If you'd like, you can select some default template that the registrar provides, such as For Sale or Under Construction, you can also direct the domain to another web address. The second option is very helpful in case you own a number of domains, but you want each and every one of them to open the same website. As an illustration, you could 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 only and the traffic to the other ones is going to be redirected to it.
