If you'd like to register a domain name to ensure that no one else will take it, but you haven't created the site for it yet, you may park it. That is a feature that registrar companies provide whenever a domain address is not linked to any web or email hosting service. By doing this, you are able to protect a brand name, for instance, and you will own the domain name in question although it will not open any content. If you'd like, you may choose some standard template that the registrar provides, such as For Sale or Under Construction, alternatively you can direct 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. For instance, you may register domain.net and domain.org, then park them and forward them to domain.com. In this example, you'll need hosting for the third domain address only and the traffic to the other ones will be redirected to it.
