T-Mobile USA has been one of the first carriers to widely deploy IPv6, seeking to overcome the lack of IPv4 addresses and to lay the foundation for their network for the Internet of Everything. However, one of the headaches they’ve faced is that some applications which work fine over IPv4 don’t play nicely with IPv6. That’s a real challenge for service providers, impacting their ability to migrate completely away from IPv4 and complicating their network operations.

T-Mobile helped author RFC 6877, which describes the 464XLAT architecture and how it enables all applications to work correctly over an all IPv6 network.  The 464XLAT architecture as well as a live demonstration was presented at V6 World Congress in Paris.

Hear from Cameron Byrne, Technical Staff Architect of T-Mobile on the development of this RFC and its implication for the widespread deployment of IPv6, along with his perspective on the remaining challenges to widespread deployment of IPv6.
