There are two services you need for a working web site - a domain and a hosting plan for it. Whenever you type the Internet 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 e-mail service, it is parked. In other words, the domain name 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” Internet page from the registrar company, or it may be directed to any other URL of your choice. The main advantage of parking a domain is that you can keep it and be sure that nobody else is going to take it. Meanwhile, it will not take a slot for a hosted domain address inside your account. In addition, you can park domain names if you have a .com, for instance, and you register domains with other extensions like .net, .org or country-code ones to direct them to the main website so as to protect a brand name.
