A parked domain is one which is taken, however it's not linked to any other service - web or e mail hosting. Basically, this type of domain address will not load any actual content if you type it in a browser, but nobody else can take it as you have already registered it and you are its owner. The main advantage of acquiring a domain and parking it afterwards is that you can keep it and not stress that someone else could possibly register it in the meantime if, for instance, the site for it is not ready yet. You can create a temporary Under Construction webpage for a parked Internet domain while you're working on your web site, or direct it to another web address - temporarily or permanently. The second option can be employed when you have already registered domain.com, for instance, and you obtain domain.net and domain.org, in order to protect a brand name or a trademark. In this case, the .net and .org domains can be parked and directed to the .com as you don't need separate websites for them.
