When configuring a class, you can set it up to allow students to select a subdomain from a domain you own.   For example, if you have marketingbyjohn.com, you can have your students choose  amazing.marketingbyjohn.com as their domain.

To setup a domain for this to work with, you will need to go to your DNS hosting company and add a * record so that it points to 52.2.164.245.   This will make every subdomain on your domain point to the DragonTeach server, so, when a student configures a subdomain, the DNS is resolved to the correct place.

Note: DNS setups can be tricky sometimes and do have the possibility of causing other things to stop working if not configured correctly.  Contact our support for help getting this working.
