If you'd like to register a domain to make sure that nobody else will take it, however, you haven't built the site for it yet, you can park it. That is a service that registrar companies offer if a domain address is not connected to any web or e mail hosting service. That way, you'll be able to protect a brand name, for instance, and you'll own the domain address in question even though it will not load any content. If you'd like, you can choose some standard template that the registrar offers, like For Sale or Under Construction, alternatively you can forward the domain name to a different web address. Your second option is very useful in case you own a few domains, but you want each and every one of them to open the same site. As an illustration, you can register domain.net and domain.org, then park them and direct them to domain.com. In this example, you are going to need hosting for the third domain name only and the traffic to the other ones is going to be redirected to it.
