It still doesn't stop handest manufatures adding DS-Lite support
and operators responding to the DHCP option so the handsets can
find the AFTR box.

NAT64/DNS64 may be the only operator side only solution but it has
lots of limitation to it and it can't be made to work as well has
DS-Lite even once the handset know the DNS64 prefix and BIH is added
to translate IPv4 to IPv6 inside the handset using the DNS64 prefix.
