If you'd like to register a domain name to make sure that no one else is going to take it, however, you haven't developed the site for it yet, you may park it. This is a service that registrar companies provide if a domain name isn't connected to any web or e mail hosting service. This way, you are able to protect a brand name, for instance, and you'll own the domain address in question even though it won't load any content. If you would like, you can choose some default template that the registrar offers, such as For Sale or Under Construction, you can also forward the domain name to an alternative web address. Your second option is extremely helpful in case you own a few domains, but you want all of them to open the same site. For instance, 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.
