A parked domain address is one which is taken, but it is not connected to another service - web or email hosting. To put it differently, such a domain won't open any real content in case 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 main advantage of acquiring a domain and parking it afterwards is the fact that you’ll be able to keep it and not worry that someone else could possibly register it meanwhile if, for example, the website for it is not ready yet. You can set a short-term Under Construction website page for a parked Internet domain while you are working on your site, or direct it to some other web address - temporarily or permanently. The second option can be employed when you have already registered domain.com, for example, and you acquire domain.net and domain.org, so that you can protect a brand name or a trademark. In such a case, the .net and .org domain addresses can be parked and directed to the .com since you do not need individual websites for them.
