There are two services you need for a working site - a domain and a website hosting plan for it. If you type the domain name in your browser, you see the content that’s uploaded in the website hosting account, but if that Internet domain isn't linked to such an account or to an e-mail service, it's parked. In other words, the domain is registered and you are its owner, but it lacks content of its own. Rather, it can open either a pre-made “Under Construction / For Sale” page from the registrar company, or it may be forwarded to any other URL of your choice. The main advantage of parking a domain is that you can keep it and be sure that no one else is going to take it. At the same time, it will not take a slot for a hosted domain address inside your account. You can also park domain names if you have a .com, for instance, and you register domain addresses 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.
