A parked domain address is one which is taken, but it is not linked to any other service - web or e-mail hosting. Basically, this type of domain will not open any real content if you type it inside an Internet browser, but nobody can take it as you have already registered it and you are its owner. The main advantage of obtaining a domain and parking it afterwards is the fact that you’re able to keep it and not worry that someone else might register it in the meantime if, for example, the site for it is not ready yet. You could set a short-term Under Construction webpage for a parked Internet domain while you're working on the web site, or direct 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 this case, the .net and .org domain addresses can be parked and forwarded to the .com because you do not need different websites for them.
