A parked domain name is one that is taken, but it is not linked to some other service - web or e-mail hosting. To put it differently, such a domain address won't load any real content when you type it in an Internet browser, but nobody else can take it as you have already registered it and you are its owner. The benefit of obtaining a domain name and parking it afterwards is the fact that you’re able to keep it and not stress that someone else might register it meanwhile if, for instance, the site for it is not ready yet. You may create a temporary Under Construction website page for a parked domain address while you're working on the website, or direct 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 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 since you don't need different sites for them.
