We're experiencing an issue while trying to use the STT service in IPv6 network. It seems to be failing at WebSocket layer. iOS 10. Any help will be very much appreciated...

The iOS SDK currently does not support IPV6.

@jasonvomsft FYI, Apple tests apps on IPv6 network and reject if they don't work, so if you want the SDK to be actually used in production you should consider supporting it. may not have been the case several months ago but we've recently been getting rejects based on this limitation.
