If you'd like to register a domain to make sure that nobody else is going to take it, however, you haven't created the web site for it yet, you may park it. It's a service that registrar companies provide whenever a domain is not linked to any web or e mail hosting service. That way, you can protect a brand name, for instance, and you will own the domain name in question although it won't open any content. If you'd like, you can choose some standard template that the registrar offers, such as For Sale or Under Construction, you can also forward the domain 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. As an example, you can 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 is going to be redirected to it.
