Does 802.11 support IPv6?

Clarifications

and it might be supported on 802.11g. I think you may need some sort of handover
for highspeed changing of assigned addresses though, there was a proposal about
that some years back. I'm not well versed in this at all, so don't take my answer as
a definitive "yes", as I'm not an authority on WiFi. Here' a link to an older IETF
article that may help...

WiFi devices that are not routers act as mac-layer bridges, so any IP version or any network layer protocol will work just fine over any 802.11 technology.
