If you'd like to register a domain name to ensure that no one else will take it, however, you have not developed the web site for it yet, you can park it. It's a service that registrar companies offer when a domain name isn't linked to any web or e-mail hosting service. By doing this, you'll be able to protect a brand name, for instance, and you'll own the domain name in question even though it will not load any content. If you would like, you can select some standard template that the registrar offers, like For Sale or Under Construction, or you can forward the domain name to a new web address. Your second option is very helpful in case you own a few domains, but you want each and every one of them to open the same website. As an illustration, you may register domain.net and domain.org, then park them and direct 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 will be redirected to it.
