A parked domain address is one that's taken, but it's not linked to another service - web or e mail hosting. Put simply, this kind of domain name won't load any actual content when you type it in a web browser, but no one can take it as you've already registered it and you are its owner. The benefit of acquiring a domain and parking it afterwards is the fact that you can keep it and not stress that somebody else might register it in the meantime if, for example, the website for it is not ready yet. You could set a short-term Under Construction webpage for a parked Internet domain while you're working on your site, or forward it to another web address - temporarily or permanently. The second option can be employed if you have already registered domain.com, for example, and you acquire domain.net and domain.org, in order to protect a brand name or a trademark. In this situation, the .net and .org domain addresses can be parked and directed to the .com since you do not need individual websites for them.
