If you wish to register a domain to make certain that nobody else is going to take it, but you haven't created the website for it yet, you may park it. This is a feature that registrar companies offer whenever a domain address is not linked to any web or e mail hosting service. In this way, you'll be able to protect a brand name, for example, and you'll own the domain in question even though it will not load any content. If you wish, you can choose some default template that the registrar provides, such as For Sale or Under Construction, alternatively you can direct the domain to a different web address. Your second option is very useful if you own a few domain names, but you want each and every one of them to open the same site. As an example, you could register domain.net and domain.org, then park them and direct them to domain.com. In this example, you'll need hosting for the third domain only and the traffic to the other ones will be redirected to it.
