A parked domain is one that's taken, however it's not associated with some other service - web or e mail hosting. Essentially, such a domain will not open any actual content in case you type it within a web browser, but no one else 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 worry that someone else might register it in the meantime if, for instance, the site for it is not ready yet. You can create a short-term Under Construction website page for a parked domain name while you are 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 since you do not need separate sites for them.
