A parked domain address is one that is taken, but it is not associated with any other service - web or e mail hosting. Put simply, this kind of domain name will not open any real content in case you type it inside an Internet browser, but no one else can take it as you have already registered it and you are its owner. The benefit of obtaining a domain and parking it afterwards is that you can keep it and not worry that someone else could possibly register it meanwhile if, for instance, the website for it is not ready yet. You can set a short-term Under Construction page for a parked domain while you're working on the site, or forward it to another web address - temporarily or permanently. The latter option can be used if you have already registered domain.com, for example, and you acquire domain.net and domain.org, in order to protect a brand name or a trademark. In cases like this, the .net and .org domain names can be parked and directed to the .com because you don't need separate sites for them.
