There are two separate services you'll need for a functioning website - a domain and a hosting plan for it. If you type the domain address in your browser, you see the content that is 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 name is registered and you're its owner, but it does not have any content of its own. Instead, it can open either a pre-made “Under Construction / For Sale” webpage from the registrar company, or it can 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 no one else will take it. At the same time, it won't occupy a slot for a hosted domain name 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 web site so as to protect a brand name.
