The cellular data industry appears to have embraced IPv6 in one form or
another.  I would expect that the network engineers have done some work
to keep IPv4 off their *internal* networks, but provide IPv4 access at
the edge.  (Isn't a netblock within IPv6 intended to enable bridging to
IPv4?)  The applications on the phon could be configured to search DNS
for AAAA addresses first.

My AT&T cell phone has both IPv4 and IPv6 addresses.  The IPv4 address
is from my access point; the IPv6 address appears to be a public address.

I would like to move to IPv6.  I just don't want to shoot myself in the
foot, or cause trouble for other people, by being sure my edge router
"follows all the rules."
