Then I guess we fully agree, and I believe I was the first one reminding that our network is a production one …
As we already had a NAT64 SSID for some time, the right step for IETF100 will be then to have a CLAT SSID, so it can be tested by those folks that want to test it.
I’m happy to help the NOC team to do that if they need help.

The actual goal of the main IETF network? From the beginning, it has
been "provide the best possible Internet connectivity to IETF
participants." Which for us today means dual stack, native IPv4 and
IPv6, and high bandwidth. That message was repeated quite loudly on the
list. The rough consensus is that any experiment should be opt-in, on a
separate network.
Would that change some day? Yes, very possibly, because of evolving
infrastructure and costs. We could see a situation where providing
native IPv4 connectivity is becoming too hard, or too expensive. If that
happened today, switching to IPv6 plus CLAT would make sense. I assume
that this is a long way from happening, but I have not seen the break
down of the costs.
As for the marketing statement today, it is simple. We do use IPv6 in a
dual stack configuration. Dual stack has been the official IPv6
transition strategy for years, so there is really nothing wrong in
saying that the IETF uses it.
