Safari is definitely preferring IPv4. In a happier note, if you tether a device via hotspot on an IOS6 iPad, the clients get native IPv6. Strangely, they get addresses out of the same /64 as the iPad's LTE interface. Anyone know how that is working? I would have thought they would use prefix-delegation, and there would be a separate routed /64.
