Interesting video; thanks for posting the link. This does seem a strange proposal though. My understanding from the video is that it is a technology to help not with the deployment of IPv6 but with the scarcity of IPv4 addresses. In summary; it simply allows a number of users (e.g. 1024) to share a single public IPv4 address. My feeling is therefore, why are the IPv4 packets to/from the end user being either encapsulated or translated into IPv6 - why do they not simply remain as IPv4 packets? If the data is kept as IPv4, this seems to come down to just two changes, * The ISP's router to which the user connects being able to route packets on routes that go beyond the IP address and into the port number field of TCP/UDP. * A CE router being instructed to constrain itself to using a limited set of ports on the WAN side in its NAT44 implementation. Why all the IPv6 shenanigans complicating matters? Cheers, aid
