Apple Will Require IPv6 Support For All iOS 9 Apps

“Because IPv6 support is so critical to ensuring your applications work across the world for every customer, we are making it an AppStore submission requirement, starting with iOS 9.
Well, it’s one more step in the right direction towards the tipping point
Most significantly, though, this step by Apple means that all the iOS apps that run on iOS 9 will work well over the IPv6-only networks that are starting to be deployed. Even in dual-stack (IPv6/IPv4) networks, this should mean that iOS 9 apps will work better in those environments when, for instance, IPv6 may be faster. (More needs to be understood here about the specifics of the IPv6 support.)
