When you create a subdomain, a directory with the name of the subdomain is created inside the public_html directory. This directory is mapped to the subdomain. For example, if you create a subdomain called sub1.yourdomain.com, a directory called sub1 will be created inside your public_html directory, files that you place inside the sub1 directory can be accessed by directing your browser to one of the following URLs: http://sub1.yourdomain.com http://yourdomain.com/sub1 All subdomains setup through the control panel draw their resources from the parent account plan.
