There are 2 services you'll need for a functioning web site - a domain name and a web hosting plan for it. Whenever you type the domain in your browser, you see the content that’s uploaded within the website 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 does not have any content of its own. Rather, 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 ensure that no one else is going to take it. Meanwhile, it will not take a slot for a hosted domain name within your account. You could also park domains if you have a .com, for instance, and you register domain addresses with other extensions such as .net, .org or country-code ones to direct them to the main web site so as to protect a brand name.
