There are 2 services that you’ll need for a working web site - a domain name and a website hosting plan for it. When you type the domain in your web browser, you see the content that’s uploaded within the hosting account, but if that domain is not linked to such an account or to an e-mail service, it is parked. To put it differently, the domain name is registered and you are its owner, but it doesn't 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 some other URL of your choice. The main advantage of parking a domain name is that you can keep it and be sure that nobody else will take it. In the meantime, it won't occupy a slot for a hosted domain inside your account. In addition, you can park domain names if you have a .com, for example, and you register domains with other extensions like .net, .org or country-code ones to direct them to the main site in order to protect a brand name.
