A parked domain address is one that is taken, but it's not associated with some other service - web or e mail hosting. To put it differently, this type of domain address won't open any real content in case you type it inside an Internet browser, but no one can take it as you've already registered it and you are its owner. The best thing about acquiring a domain and parking it afterwards is the fact that you are able to keep it and not stress that someone else may register it in the meantime if, for example, the website for it is not ready yet. You are able to set a short-term Under Construction webpage for a parked domain name while you're working on the web site, or forward it to some other web address - temporarily or permanently. The second option can be used 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 cases like this, the .net and .org domain addresses can be parked and forwarded to the .com because you do not need different sites for them.
