i suspect we do not disagree, but just to clarify.

fixed operators (in the non-wireless-phone sense) need to support home,
enterprise, etc. customers who will have both ipv4 and, we hope, ipv6
needs for a while.  so we need to deploy ipv6 *along side* ipv4, i.e.
dual stack.  stateless translation tools do not scale or perform well at
isp backbone scale.

our dual stack edge customers will use our dual stack backbones in a
simple fashion, no impedance matching needed.  the ipv6-only customer
will need nat64/dns64 to reach legacy ipv4-only destinations.

the ipv4-only customer will use ______ to reach ipv6-only destinations?
