RE: IPv4 Outage Planned for IETF 71 Plenary

+1

The press reaction is likely to be better as well.

The only point to doing the IPv6 only approach is if you want to demonstrate that it is entirely impractical and drill it into folks heads that we need to be more realistic in our approach here.

The double NAT approach is much closer to what the actual transition is going to look like. The only difference is that I think we might just be able to work out a viable means of punching holes so that video-conferencing works if we actually set our minds to it.

I strongly support this experiment and believe it would be a really
good idea to run.  I do think behave-compatible nats should be used,
but besides that, I think the experiment you propose is far more
valuable than the v6-only experiment.
