There are 2 services that you’ll need for a functioning website - a domain name and a website hosting plan for it. If you type the domain in your browser, you see the content that is uploaded in the web hosting account, but if that domain name isn't linked to such an account or to an e-mail service, it's parked. Put simply, the domain is registered and you're its owner, but it lacks content of its own. Instead, it can open either a pre-made “Under Construction / For Sale” webpage from the registrar company, or it may be forwarded to any other URL of your choice. The main advantage of parking a domain is that you can keep it and ensure that no one else is going to take it. In the meantime, it won't occupy a slot for a hosted Internet domain within your account. You may also park domains 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 site so as to protect a brand name.
