I suspect what Mr. Townsley and Mr. Arkko are aiming at here is that if FUN c
an come up with a scheme to make routed home subnetworks work with delegated
IPv6 prefixes, then it is probably not too far-fetched that the same scheme c
ould be trivially extended for assigning IPv4 subnets from the RFC 1918 priva
te realm to support dual-stack routed home subnetworks.
I'm not expecting home networks to be able to run IPv6-only with the IPv4 Int
ernet mapped to 64:ff9b::/96 through NAT64 for several more years yet. There
's a whole crapload of legacy IPv4-only devices in the average home theater s
ystem today that nobody wants to cut off from the Internet just yet.
I'm expecting home nets to be dual stacked for 10+ years after IPv6
is common to the home (2-5) years. If the home gateway has DS-Lite
support then that provides a better solution than NAT 444. It also
continues to work when the home net goes IPv6 only with the home
gateway passing on the DS-Lite parameters from the ISP.
Consumer electronics lasts 10+ years. I'm still using my DOCSIS
1.0 modem 8+ years. My router hardware is 13+ years old, the
software is newer and is the 6in4 tunnel end point. I've got TV's
of similar vintage.
