NetworkReachability.ReachableViaLocalAreaNetwork Broken for IPv6?

Our app got rejected by Apple due to “IPv6” incompatibilities, and judging from the logs/screenshots, it’s because of our WiFi check where we do:

bool wifiAccessible = Application.internetReachability ==
                NetworkReachability.ReachableViaLocalAreaNetwork;

We’re trying to repro the issue on an IPv6 network at the moment but wondering - is the Application.internetReachability broken on a pure-IPv6 network? We’re using Unity 5.4.0f3.

Nevermind… Looks like the issue is in Apple’s Network. They redid the submission tests and everything looks good to go.
