OK Randy. How about a suggestion that is useful.
My approach thus far absent CPE support for transition mechanisms has been native IPv6 across the board + NAT444, but I use a VRF to regionalize the NAT444 routing and bring it to a semi-centralized gateway much like one would using DS-Lite, 464XLAT, MAP, LW4o6, etc. No need to forklift anything, and you can deploy whatever suits you incrementally in regions where you need to. It also works with all user-supplied CPE routers which is a bonus as I hate to require that users use my CPE router, and it's not yet easy for consumers to verify beforehand that the router they're buying at Best Buy will support any particular transition tech, though I'd really like to get that fixed. I'm quite small, though. I can imagine this would be a hassle compared to running a single stack access layer at scale, and of course the NAT is stateful no matter what you do with this technique. -- Brandon Martin
