A parked domain address is one which is taken, but it is not connected to any other service - web or e-mail hosting. Essentially, this kind of domain will not open any real content when you type it within a web browser, but no one can take it as you've already registered it and you are its owner. The main advantage of obtaining a domain and parking it afterwards is that you’re able to 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 may set a short-term Under Construction webpage for a parked Internet domain while you're working on the website, or direct it to another web address - temporarily or permanently. The latter option can be used 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 cases like this, the .net and .org domain addresses can be parked and directed to the .com since you don't need individual websites for them.
