If ATM, Apple Talk and Novel IPX were IETF standards, could we declare them historic. Yes, because no one is using anymore.
ATM, DECnet, and other old protocols are still in use. They’re just not Internet protocols, so we don’t see them.
Can we do the same with IPv4, no, because 90% of the Internet is using it.
When could we declare IPv4 as historic? As Geoff mentioned, when we reach 99% of IPv6 use (probably he said something different but he point was when IPv4 is barely used in the Internet)
We have spend 15 years trying to push IPv6, not just the IETF but many in the Internet community, the result we all know.
Yes, 11% of the world is using it, with a curve suggesting 30% in 2018 and 80% in 2020. That’s only four years away.
So, do we honestly think that an RFC document would declaring IPv4 as historic would convince many networks operators to deploy IPv6 when even the IPv4 exhaustion didn't?
I would ask, what is the goal of the document?
I tried to say in the document, but I understand I didn’t say it well. The goal is for the IETF to stop working on IPv4. There are no more enhancements to be had in IPv4. Our time and energy would be better spent optimizing IPv6 than extending IPv4.
If it is to declare a protocol as historic because it is not longer used enough and we should not do more work, then I think is not time yet.
If it is to make awareness that we need to deploy more IPv6 and stop using IPv4, the impact would be minimal compared to the complications that it would create.
As discussed in other places (sunset, the session, etc.) I would found more value in a document setting the path to make IPv4 historic.
Yes, I heard that. What path do you think we should set?

I think we need to avoid confusing people.
Deprecating IPv4 doesn’t means that it can’t be used anymore. It means that we want to make sure people start thinking in IPv6, using it as much as possible and using IPv4 as less as possible.
It also means that new features will not be developed for IPv4 and possibly bugs at the protocol level (if discovered) will not be sorted out.
Nobody will disconnect you from IPv4 now, but sooner or later it may happen.
Is like analogue and digital TV, of course, at the end, you will get disconnected from analogue TV, but you will be able to have devices that still get you working on Internet, such as the CPE performing some transition (464XLAT, for example). This is normal life cycle for everything in the world !
