In our Developer Plan up to 5 "add-on domains" can be created to a subdomain in your master account. After creating an "Add-on Domain " you can set your Name Servers for the domain (at your registrar) to:

NS1.JCNETWORKS.NET, NS2.JCNETWORKS.NET

The domain will automatically resolve to the subdomain folder in your master account. This feature is very helpful for webmasters developing a new site for a client.

Parked domains are parked on top of the main domain. yourparkeddomain.com; will point to your maindomain.com and resolve to it just like the main domain name..
