There are two services that you’ll need for a working website - a domain and a website hosting plan for it. When you type the domain address in your web browser, you see the content that is uploaded within the website hosting account, but if that domain address isn't linked to such an account or to an e-mail service, it is parked. To put it differently, the Internet domain is registered and you're its owner, but it does not have any content of its own. As a substitute, it can open either a pre-made “Under Construction / For Sale” Internet page from the registrar company, or it can be forwarded to some other URL of your choice. The main advantage of parking a domain address is that you can keep it and be sure that nobody else is going to take it. Meanwhile, it's not going to occupy a slot for a hosted Internet domain inside your account. You can also park domain names 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 web site so as to protect a brand name.
