I have a 2013 environment that i have exposed to the internet using SSL and am working on the App Management Service Provisioning for this farm.
First Question is, will i need to buy a public domain name for the internal app DNS domain zone i have setup internally? what could be expected if i did not buy a domain for this need and a user was working with a site that had an app enabled?
Secondly, I have a production farm and development farm, when provisioning the app management service will i also need to setup a zone in DNS like i did for production (apps-mycompany.com) that is specifically for development (appsdev-mycompany.com)? or am i able to use the one zone i created for production to rule them all?
