There are two services you'll need for a working site - a domain name plus a hosting plan for it. Any time you type the domain in your browser, you see the content that’s uploaded inside the web hosting account, but if that domain address isn't linked to such an account or to an email service, it's parked. To put it differently, the Internet domain 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” page from the registrar company, or it can be forwarded to any other URL of your choice. The main benefit of parking a domain name is that you can keep it and make certain that no one else is going to take it. Meanwhile, it will not take a slot for a hosted domain name within your account. You can also 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 website as a way to protect a brand name.
