A parked domain is one which is taken, however it's not associated with another service - web or email hosting. Basically, this kind of domain name will not load 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 main advantage of getting a domain name and parking it afterwards is the fact that you’re able to keep it and not stress that someone else could possibly register it meanwhile if, for instance, the site for it is not ready yet. You could create a temporary Under Construction webpage for a parked domain name while you're working on your 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 obtain domain.net and domain.org, in order to protect a brand name or a trademark. In such a case, the .net and .org domain addresses can be parked and forwarded to the .com because you do not need individual websites for them.
