There are two separate services that you’ll need for a functioning site - a domain plus a web hosting plan for it. When you type the domain address 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. To put it differently, the domain address 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” webpage from the registrar company, or it may be directed to any other URL of your choice. The main benefit of parking a domain address is that you can keep it and make certain that nobody else is going to take it. In the meantime, it's not going to block a slot for a hosted domain name within your account. You could also park domain names if you have a .com, for instance, and you register domain names with other extensions like .net, .org or country-code ones to forward them to the main web site as a way to protect a brand name.
