A parked domain address is one that is taken, yet it is not linked to another service - web or email hosting. To put it differently, such a domain address won't load any actual content in case you type it within a browser, but no one can take it as you've already registered it and you are its owner. The advantage of obtaining a domain name and parking it afterwards is that you’re able to keep it and not stress that somebody else could possibly register it meanwhile if, for instance, the website for it is not ready yet. You may set a temporary Under Construction page for a parked domain address while you are working on your site, or forward it to another web address - temporarily or permanently. The latter option can be employed if you have already registered domain.com, for instance, and you get domain.net and domain.org, in order to protect a brand name or a trademark. In this case, the .net and .org domains can be parked and forwarded to the .com since you do not need different sites for them.
