I have no doubt that a combination of IPv6 native and network provided CLAT will work. It effectively provides devices with a dual stack service, native IPv6 and natted IPv4. We know that dual stack works -- it has been the default service on the main IETF network for years. We also know that natted IPv4 kind of works -- that's what most customers have been getting for many years, and most applications have adapted by now. But then, why deploy that on the main IETF network? IPv6 plus natted IPv4 is definitely less cool than IPv6 plus native IPv4, which is what the network has traditionally provided. -- Christian Huitema -- Christian Huitema
