There are 2 services that you’ll need for a functioning website - a domain name plus a website hosting plan for it. When you type the domain in your web browser, you see the content that’s uploaded in the website hosting account, but if that domain address isn't linked to such an account or to an email service, it's parked. In other words, the domain name is registered and you're 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 forwarded to some other URL of your choice. The main benefit of parking a domain is that you can keep it and be sure that nobody else will take it. At the same time, it's not going to block a slot for a hosted Internet domain inside your account. You may also park domain names if you have a .com, for example, and you register domain names with other extensions such as .net, .org or country-code ones to forward them to the main web site in order to protect a brand name.
