There are two services you'll need for a functioning site - a domain and a hosting plan for it. Any time you type the domain address in your web browser, you see the content that’s uploaded inside the web hosting account, but if that domain isn't linked to such an account or to an e-mail service, it's parked. Put simply, the domain name is registered and you are its owner, but it does not have any content of its own. Rather, it can open either a pre-made “Under Construction / For Sale” Internet page from the registrar company, or it could be forwarded to any other URL of your choice. The advantage of parking a domain address is that you can keep it and ensure that nobody else will take it. In the meantime, it will not occupy a slot for a hosted Internet domain in your account. In addition, you can park domain names if you have a .com, for example, and you register domain addresses with other extensions such as .net, .org or country-code ones to forward them to the main site so as to protect a brand name.
