There are 2 services you'll need for a functioning web site - a domain and a web hosting plan for it. Whenever you type the domain in your web browser, you see the content that’s uploaded within the web hosting account, but if that domain is not linked to such an account or to an e-mail service, it is parked. In other words, the Internet domain is registered and you are its owner, but it lacks content of its own. As a substitute, 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 benefit of parking a domain is that you can keep it and ensure that no one else is going to take it. At the same time, it will not occupy a slot for a hosted domain name inside your account. You can also park domain names if you have a .com, for example, and you register domains with other extensions like .net, .org or country-code ones to forward them to the main site in order to protect a brand name.
