Tbh ipv4 and cgnat im hoping at this point will go the way of POTS and be something we force turn off. There are differences between how ipv6 works and v4 ….
But I’m not sure the cost of running these shims for forever is worth what they’re holding back.
The only question remaining in my mind is if the world is ready for ipv6 … but maybe it’s better if we at least set a date.
