Uploading app to App Store(IP V6 problem)

It's a simple daily quote app. It displays quotation retrieved from mssql database. Development was finished. All of the features of app was implemented perfectly. But, During upload it to app store, it was rejected by Apple because it is not IPv6 Compliant. I thought maybe it was because the IP Address literal for the sql server was hard coded in the program so I replaced it with the hostname but that was rejected by Apple as well. Here is what they said: _______________________ We discovered one or more bugs in your app when reviewed on iPad and iPhone running iOS 10.1 on Wi-Fi connected to an IPv6 network. Specifically, no content appears for any chosen day. We've attached screenshot(s) for your reference. Next Steps Please run your app on a device while connected to an IPv6 network (all apps must support IPv6) to identify the issue(s), then revise and resubmit your app for review. If we misunderstood the intended behavior of your app, please reply to this message in Resolution Center to provide information on how these features were intended to work. For new apps, uninstall all previous versions of your app from a device, then install and follow the steps to reproduce the issue(s).
