There are two services you'll need for a working web site - a domain name and a hosting plan for it. Whenever you type the domain address in your browser, you see the content that’s uploaded within the website hosting account, but if that domain address isn't linked to such an account or to an email service, it is parked. To put it differently, the domain is registered and you are its owner, but it does not 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 some other URL of your choice. The main benefit of parking a domain is that you can keep it and be sure that nobody else is going to take it. At the same time, it will not take a slot for a hosted Internet domain within your account. You may also park domains if you have a .com, for example, and you register domain names with other extensions like .net, .org or country-code ones to forward them to the main site as a way to protect a brand name.
