If you want to register a domain to make sure that no one else will take it, but you haven't built the site for it yet, you may park it. This is a feature that registrar companies provide when a domain is not 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 even though it won't load any content. If you wish, you can select some default template that the registrar offers, such as For Sale or Under Construction, or you can direct the domain name to a different web address. The second option is extremely helpful in case you own a few domain names, but you want each and every one of them to open the same site. For example, you could register domain.net and domain.org, then park them and forward them to domain.com. In this example, you're going to need hosting for the third domain name only and the traffic to the other ones is going to be redirected to it.
