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 see that deploying WiFi IPv6 today is at least a challenge, and definitely a risk. Android, for example, doesn't yet support DHCPv6 on WiFi (it's not needed on the carrier side, which does DNS intercept), and intermittently looses its unicast address on some hardware devices (notably tablets, in my experience). 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. -mel beckman

IPv6 is "allowed for in the future" but not configured in the short term. With less than 10,000 ephemeral users, we don't expect users to demand IPv6 until most mobile devices and apps come ready to use IPv6 by default.I didn¹t see anybody point out that most mobile devices and apps come ready to use IPv6 by default. At least, all Android and iOS devices do, and Apple recently announced that IPv6 support will be mandatory in future apps. Plus, Facebook, at least, says IPv6 is faster over mobile. Don¹t know how it does over Wi-Fi. Lee
