There are two services that you’ll need for a functioning web site - a domain plus a web hosting plan for it. When you type the domain in your web browser, you see the content that is uploaded within the web hosting account, but if that domain name is not linked to such an account or to an e-mail service, it is parked. Put simply, the domain address is registered and you are its owner, but it doesn't have any content of its own. Instead, it can open either a pre-made “Under Construction / For Sale” webpage from the registrar company, or it could be forwarded to any other URL of your choice. The main advantage of parking a domain address is that you can keep it and be sure that no one else will take it. In the meantime, it won't take a slot for a hosted Internet domain inside your account. You may also park domains if you have a .com, for instance, and you register domains with other extensions like .net, .org or country-code ones to forward them to the main website in order to protect a brand name.
