Fixed subject line. The original thread doesn't need any more noise.

Please clarify:

Won't get an IPv6 address when placed on a proper IPv6-capable wifi
segment that does SLAAC, or won't do IPv6 over mobile, or you simply
haven't seen anything that proves it's doing those things? Note that in
this version of Android, you may need a third-party application or a
command line to see the IPv6 address on either Wifi or mobile interfaces
unless you're willing to capture packets as they go past on the network or
can find a website that confirms you're reaching it via IPv6, because it
didn't have any IPv6 stuff in the UI despite supporting it pretty well.
There's an app called Network Info II that will help with this.
The reason I ask is that the former is broken Android, whether
intentionally or not. The latter is mobile provider dependent, and it
makes a difference when asserting "I bought something for sale today that
doesn't support IPv6".

Thanks,

Wes
