I wish to setup OS X Server as MDM server to manage a dozen iPads for our church. Having trouble finding answers. Would someone please let me know if the server can be local, or has to be available over the Internet? We have our domain and website with a web hosting company. If we need to have the server over the Internet, I will need to mess with the DNS entries, and not sure what we need as the server will be running from the church which has a different ip to the rest of the web server being hosted.
