And those phones are behind an equivalence of CGNAT so the whole dream of "no NAT" is utterly not true for most IPv6 deployments.
Only for IPv4 destinations however, where there is no other way. For IPv6 destinations it's just native connectivity with no NAT.
Through a stateful firewall which blocks all incoming connections, completely invalidating "every device accessible" tenet of IPv6 and bringin zero value to the actual customers.
APNIC stats show that assigned IPv6 /32 prefixes are still growing YoY. Wouldn't call that stagnating.
