There are two services that you need for a working web site - a domain and a hosting plan for it. If you type the domain name in your Internet browser, you see the content that’s uploaded inside the website hosting account, but if that domain isn't linked to such an account or to an e-mail service, it's parked. To put it differently, the domain name 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” Internet page from the registrar company, or it may 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 is going to take it. At the same time, it won't take a slot for a hosted domain address inside your account. You may also park domains if you have a .com, for example, and you register domain names with other extensions like .net, .org or country-code ones to direct them to the main website so as to protect a brand name.
