A piece of client software is installed on every phone that presents an IPv4 address to the phone and then translates packets to IPv6 for relay over the network. This works because T-Mobile has considerable control over the phone. https://www.internetsociety.org/resources/deploy360/2014/case-study-t-mobile-us-goes-ipv6-only-using-464xlat/ Regards, Bill Herrin -- William Herrin b...@herrin.us https://bill.herrin.us/
