A parked Internet domain is one which is taken, however it's not linked to some other service - web or e mail hosting. Put simply, this kind of domain address will not open any real content when you type it within a web browser, but nobody else can take it as you've already registered it and you are its owner. The benefit of getting a domain name and parking it afterwards is that you can keep it and not stress that somebody else might register it meanwhile if, for example, the website for it is not ready yet. You can set a short-term Under Construction page for a parked domain while you are working on your website, or forward it to some other web address - temporarily or permanently. The second option can be employed if you have already registered domain.com, for instance, and you obtain domain.net and domain.org, so as 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 don't need separate sites for them.
