If you want to register a domain to make sure that no one else will take it, but you haven't built the web site for it yet, you may park it. This is a feature that registrar companies provide if a domain name isn't connected to any web or e mail hosting service. By doing this, you are able to protect a brand name, for example, and you'll own the domain name in question even though it will not open any content. If you would like, you may choose some default template that the registrar provides, such as For Sale or Under Construction, you can also direct the domain to another web address. The second option is very helpful in case you own a number of domains, but you want each and every one of them to open the same website. For example, 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 address only and the traffic to the other ones will be redirected to it.
