If that's an experiment, wow. 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."
