If you'd like 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 may park it. That is a feature that registrar companies offer whenever a domain isn't connected to any web or e mail hosting service. In this way, you are able to protect a brand name, for instance, and you'll own the domain in question although it won't load any content. If you wish, you can pick some default template that the registrar offers, like For Sale or Under Construction, you can also forward the domain name to a different web address. Your second option is very useful in case you own a few domain names, but you want all 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 will need hosting for the third domain name only and the traffic to the other ones is going to be redirected to it.
