There are 2 services you need for a working site - a domain name and a hosting plan for it. Any time you type the domain name in your Internet browser, you see the content that is uploaded within the website hosting account, but if that domain address is not linked to such an account or to an e-mail service, it's parked. In other words, the domain name is registered and you are its owner, but it lacks content of its own. Instead, 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 benefit of parking a domain name is that you can keep it and ensure that nobody else is going to take it. At the same time, it won't occupy a slot for a hosted domain inside your account. In addition, you can park domains if you have a .com, for example, and you register domain names with other extensions such as .net, .org or country-code ones to forward them to the main web site as a way to protect a brand name.
