There are two services that you’ll need for a functioning site - a domain and a hosting plan for it. Whenever you type the Internet domain in your browser, you see the content that is uploaded within the hosting account, but if that Internet domain 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. Rather, it can open either a pre-made “Under Construction / For Sale” webpage from the registrar company, or it can be forwarded to any other URL of your choice. The main advantage of parking a domain name is that you can keep it and ensure that no one else will take it. In the meantime, it will not take a slot for a hosted Internet domain inside your account. You can also park domain names if you have a .com, for example, and you register domains with other extensions such as .net, .org or country-code ones to direct them to the main website as a way to protect a brand name.
