A parked domain address is one that is taken, but it's not connected to any other service - web or email hosting. Put simply, this kind of domain will not load any real content if you type it inside a browser, but no one can take it as you've already registered it and you are its owner. The advantage of acquiring a domain and parking it afterwards is the fact that you’re able to keep it and not stress that somebody else may register it in the meantime if, for example, the website for it is not ready yet. You are able to set a temporary Under Construction page for a parked domain address while you are working on the website, or forward it to another web address - temporarily or permanently. The second option can be employed when you have already registered domain.com, for example, and you get 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 forwarded to the .com as you do not need individual sites for them.
