In my country, the last big _mobile_ internet provider finished its move to IPv6.

Land lines internet have been IPv6 for more than a decade.

While developping custom IPv6 internet software I am not blocked by NAT anymore, real p2p fiesta, everything works as intended.

The real challenge now is IPv6 with fixed mobile internet address (not random as it is is now, it should be device uniq). That to replace for good the phone numbers (the challenge of international roaming... which is already done for phone numbers). The idea would be to avoid a third party centralized internet account->ipv6 mapping.
