they could continue to use their Win95 machine, but they would need to upgrade their router (the router would need to do IPv4 -> IPv6 NAT

I'm glad to see the NAT64 proposal, it's long overdue.

the silly thing about all of this is that IPv6 allocated a tiny slice of it's address space to include all the IPv4 addresses. This is a very straightforward mapping of conventional NAT processes, it's too bad that it's taking this long to get approved.

do you know if there is any software implementing this yet?

There's this:

It looks a little rough around the edges though.

I'm also concerned that what they are working with is so old

bind 9.6-p1 when the current is 9.7.2-p2, fedora 10-12 (14 will be current in a couple of days, at which point 12 hits EOL)

all of this stuff is at least a year old at this point. I would have hoped that this sort of functionality would be getting upstream at this point.

the IETF draft document is set to expire in Jan 2011, so if it's going to become a standard instead of just fading away it's rapidly running out of time.

It's not meant to be production-quality software. Real deployments use proprietary implementations like the A10 Networks stuff. I haven't really seen anybody want to run NAT64 outside the carrier world.

The NAT64 draft cleared last call in August and is in the RFC Editor queue waiting on some related drafts to be done before it's published as an RFC.

with something like like this I would expect that a lot of people would want to use it in small settings, simply for the bragging rights :-)

if something like this were to be added upstream (into linux, BSD, and the two nameserveer packages) you would see this capibility in everything in a relativly short time. It would be trivial to add it to most small routers for example.

If they really are taking the attitude that only large ISPs would care about this and they will buy specialized equipment from Cisco to do this, then they are really missing the boat.
