What allows them to work with v6 in such an efficient manner? 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.
FWIW, this software component (the CLAT) can also be on the CPE edge router which many ISPs either control outright these days or at least can influence. -- Brandon Martin
Correct, and T-Mobile uses this 464xlat approach for their home broadband product as well
