If you wish to register a domain to make sure that nobody else is going to take it, however, you have not created the site for it yet, you may park it. This is a feature that registrar companies provide whenever a domain isn't linked to any web or e mail hosting service. That way, you can protect a brand name, for example, and you will own the domain name in question even though it will not load any content. If you'd like, you may choose some default template that the registrar offers, such as For Sale or Under Construction, or you can direct the domain name to a new web address. Your second option is very helpful in case you own a few domain names, but you want each and every one of them to open the same website. For example, you could register domain.net and domain.org, then park them and direct them to domain.com. In this example, you'll need hosting for the third domain name only and the traffic to the other ones is going to be redirected to it.
