IPv6 & Apple

[Scott Rossi]

I recently received an app review response from Apple stating my app has
connection issues when connecting to a server on an IPv6 network:

"We discovered one or more bugs in your app when reviewed on iPad and
iPhone running iOS 9.3.4 on Wi-Fi connected to an IPv6 network.

Your app shows an error message upon launch and after login. Screenshot of
this issue has been attached for your reference. 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."

Does anyone have any experience with this?  The backend database guy I'm
working with thinks this is a hosting issue (host needs to support IPv6).
Will switching to a host that supports the new protocol allow us to
troubleshoot/fix this?

Thanks & Regards,
