Hi John, I know this is a difficult topic, and we don't enforce the vendors, but we do "de facto".
I mean, if a vendor don't pass a given RFC in a conformance/interoperability, because they do NAT, then a lot of customers (ISPs, Telcos) will not purchase it, because that's what the market do most of the time. And this is a "market" enforcement ... What about something like: IPv6 has enough addressing space that allows avoid the need of any kind of address translation, that is considered harmful according [RFCxxxx]. Consequently, IPv6 nodes MUST NOT support any kind of address translation.

I feel ambigious about this - avoiding NATs is a good thing, however IETF is not a protocol enforcement agency. Interop & conformance testing happens outside of the IETF, so I am not sure this is in scope for the IETF. Additionally, the WG chairs chartered the Node Requirements work to document existing requirements, and I actually don't think we have any IPv6 RFCs that have any related statements like 'You MUST NOT NAT IPv6' ... so I am unsure how to procede on this subject. That noted, there are well known RFCs published already on the dangers of NATing, so I'm not sure what good it would do to put something in the Node Requirements document. Finally, I actually don't know what a reasonable requirement would be to add to cover this. If you think you have good text, please send it on the mailing list.
