Android doesn't respect/implement DHCPv6. But there are IPv6 privacy extensions that periodically rotate the IPv6 addresses of the device.

Thanks for the reference! Doing that directly with SLAAC is of course even nicer.
In that scenario, DHCPv6 would be responsible for keeping the assigned subnet filled randomly, rather than being conservative and consistent with address assignments. I don't know if anyone is doing it now, but I don't think we should dismiss IPv6 for this reason.
