I've done fairly extensive testing, and IPv6 support, while pretty solid on=
the carrier side, is still iffy on WiFi. Both iOS and Android have various=
reliability problems with IPv6 and WiFi, mostly related to acquiring a DNS=
address or maintaining a connection while roaming. Combine that with less-=
than-fully-baked IPv6 on some enterprise WiFi platforms, and it's easy to s=
ee that deploying WiFi IPv6 today is at least a challenge, and definitely a=
risk.=20
Android, for example, doesn't yet support DHCPv6 on WiFi (it's not needed o=
n the carrier side, which does DNS intercept), and intermittently looses it=
s unicast address on some hardware devices (notably tablets, in my experien=
ce). Even when android gets DHCPv6, or these hardware problems get solved, =
there will be several years of legacy devices in the field to contend with.=
