If you'd like to register a domain to ensure that nobody else will take it, but you haven't developed the website for it yet, you could park it. It's a service that registrar companies offer when a domain address isn't connected to any web or e-mail 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 load any content. If you want, you may choose some default template that the registrar provides, such as For Sale or Under Construction, alternatively you can forward the domain to another web address. The second option is very useful if you own a number of domains, but you want every one of them to open the same website. For example, you could 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 will be redirected to it.
