And by the way … At some point the NAT64 service, instead of being provided by the ISP it will make sense to be provided by third party companies, even if there is some extra delay to reach a remote NAT64, etc., and even if there is an extra cost for that customer that still requires it.

It is clear to me that hotel rooms need to provide IPv6 + IPv4-as-a-service (for example using a CE or AP with CLAT). The hotel network or its access can be IPv6-only and then the ISP provide the NAT64. I’m sure someone will argue that this means perpetuating IPv4: Is not the case. The case is being realistic about what an ISP or an hotel or any other organizations NEEDs to provide to their customers if they want to keep them. If the hotels provide IPv6 + IPv4-as-a-service, the customer is happy and more and more traffic is moving from IPv4 to IPv6 in a natural way. If some app developers don’t see it, or if some content providers or enterprises where the VPN is being connected, there will be a point where the IPv4 traffic is meaningless and they have the risk that at that point the IPv4-as-a-service is not offered anymore, not because the cost of the CLAT, but because the cost of the NAT64. The only way we can motivate all them to move to IPv6 is to make sure that when, for example 75% of the Internet traffic is IPv6, we clearly announce that IPv4 is historical, has not maintenance, and will be dropped and unsupported and will not be able to be reachable. It is the ISPs work to decide if they want to keep providing NAT64 or not, and to tell their customers. At some point, more and more ISPs will drop that service. Wherever that point is at the 75% of IPv6 traffic or 95% or something in the middle is to be decided by each ISP, also maybe depending on their competitors, etc. I recall a few years ago when a phone company in Spain still had a few customers with old “pulse disk phones”. They took the decision to cancel the contract to those customers if they don’t want to get the phone replaces with DTMF phones. Same today is happening with customers with ADSL where there is GPON coverage. You accept to be replaced to GPON, or they cancel the contract, because it is more expensive to keep a few “old fashioned” customers that the profit they generate.

Many IETF people are developers or work for companies having applications not working. > As I said there were a minimum of applications that didn't work. Corporate VPNs largely did. Jen has the final numbers. However, as long as even one application, such as one VPN, or one literal IPv4 address, fails, that represents millions of failure cases if we consider the whole world (e.g. imagine every hotel network in the world running IPv6+NAT64 only). That simply isn't viable. Dual stack in every hotel room in the world is viable, from the hotel guests' point of view. Operators might not like it, but users wouldn't care.
