A parked domain name is one that's taken, yet it is not associated with another service - web or e-mail hosting. In other words, this kind of domain address will not load any actual content if you type it in a browser, but nobody else can take it as you've already registered it and you are its owner. The best thing about getting a domain name and parking it afterwards is that you’re able to keep it and not worry that someone else could possibly register it in the meantime if, for instance, the site for it is not ready yet. You can set a temporary Under Construction webpage for a parked domain while you are working on the web site, or direct it to some other web address - temporarily or permanently. The latter option can be employed when you have already registered domain.com, for example, and you get domain.net and domain.org, so that you can protect a brand name or a trademark. In cases like this, the .net and .org domain addresses can be parked and directed to the .com since you do not need individual sites for them.
