There are two separate services you'll need for a working web site - a domain plus a website hosting plan for it. If you type the domain address in your Internet browser, you see the content that is uploaded within the hosting account, but if that Internet domain is not linked to such an account or to an e-mail service, it's parked. Put simply, the Internet domain is registered and you're its owner, but it doesn't 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 could be directed to some other URL of your choice. The advantage of parking a domain name is that you can keep it and make sure that no one else will take it. At the same time, it will not block 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.
