If you'd like to register a domain to ensure that no one else will take it, but you have not developed the website for it yet, you may park it. That is a service that registrar companies provide if a domain address isn't connected to any web or e-mail hosting service. That way, you are able to protect a brand name, for instance, and you will own the domain in question even though it will not open any content. If you wish, you can select some default 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 useful in case you own a few domains, but you want every one of them to open the same website. As an example, 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 address only and the traffic to the other ones will be redirected to it.
