The vision of T-mobile USA for the near future: IPv6 is the network protocol, IPv4 is "legacy" and will be hidden behind NAT64 gateways. Content providers better take note:"Our users are going to access your content over IPv6. The only relevant question is 'will we make the AAAA record or will you?' Wouldn't you rather be the one to do it so you have control?"Time for content-providers to think about IPv6 strategy. Via T-Mobile is pushing IPv6. Hard. - Living with IPv6.
