    So we have a standard way of delivering IPv4 over wifi. It actually works.
    It is used by billions of people every day without even thinking about it.
    By all measures a great success.
    
    We also have a way of delivering IPv6 over wifi. In typical IETF fashion 
    we try to break that as much as possible. But it can be made to work.
    
    So obviously this is way too boring. We have both IPv4 and IPv6 that work.
    We need to do something, anything.
    
    So NAT64 enters the stage. At first NAT64 was used to solve a problem in
    the mobile networks where you cannot have dual stack for reasons only telco's 
    understand.

[Jordi] Because we don’t have any more IPv4 public addresses, and we know that for some time, we will need to access still some old “IPv6-only” resources? Sharing IPv4 addresses by means of NAT64 is one solution to that.
    
    But now we can use that same technology to spice up the wifi landscape a bit
    more.
    
    First we confusingly call it 'IPv6-only'. There is nothing IPv6-only about
    NAT64. It is a technology specifically designed to provide access to the
    IPv4 world.
    
    Then, because of the fancy name 'IPv6-only' we claim it is the future. No
    need to justify why modifying all hosts and making the whole system more
    complex would be a reasonable future.

[Jordi] Agree, see: https://tools.ietf.org/html/draft-palet-ietf-v6ops-ipv6-only-00
    
    We have something that works today. We have plenty of experience delivering
    what works today. No need to push overly complex technologies that offer
    nothing more than a fancy name. That's not engineering, that's a hobby.
    
[Jordi] We need to move to IPv6-only “all”, there is an intermediate step, for “some” (crystal ball) years, which is IPv6-only-WAN, but dual-stack in the LAN. NAT64+CLAT provides it seamless across both wireline, WiFi and cellular networks.
