There are two separate services that you’ll need for a functioning web site - a domain and a hosting plan for it. Each time you type the domain name in your Internet browser, you see the content that is uploaded inside the hosting account, but if that domain name is not linked to such an account or to an e-mail service, it is parked. To put it differently, the domain address 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 may be directed to any other URL of your choice. The benefit of parking a domain address is that you can keep it and make sure that nobody else will take it. At the same time, it won't take a slot for a hosted domain inside your account. In addition, you can park domain names if you have a .com, for instance, and you register domains with other extensions such as .net, .org or country-code ones to forward them to the main web site so as to protect a brand name.
