There are two services you need for a working site - a domain plus a hosting plan for it. When you type the domain name in your Internet browser, you see the content that’s uploaded in the website hosting account, but if that Internet domain isn't linked to such an account or to an e-mail service, it is parked. Put simply, the domain is registered and you are its owner, but it does not have any 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 can be directed to some other URL of your choice. The benefit of parking a domain address is that you can keep it and make sure that nobody else is going to take it. Meanwhile, it will not take a slot for a hosted domain inside your account. You can also park domains if you have a .com, for instance, and you register domain names with other extensions like .net, .org or country-code ones to direct them to the main website in order to protect a brand name.
