Hi NANOG,
I'm looking for some information on the four largest US mobile phone carriers and the current state of their IPv6 infrastructure. Specifically, we are trying to figure out:
1. How much of the carrier core and edge for AT&T, Verizon. T-Mobile, and Sprint are on IPv6 now?
Hi, T-Mobile USA has native ipv6 to all subscribers in all of it's coverage area. But, less than 1% of subscribers use IPv6 because they do not have an IPv6 capable phone. The Nexus S and Galaxy Nexus work well. This device challenge will improve in time. Samsung is doing a good job of bringing IPv6 to Android devices.

2. If, and how, are they handling NAT64 for native IPv6 edge devices?
Yes, NAT64 / DNS64 is used in the case of reaching ipv4-only nodes. If you are concerned about middleboxs, you should deploy IPv6.
3. What is the percentage of breakdown for users on native IPv6? Dual stacked?
GREE is a mobile social gaming company and we're trying to better understand what lies between our customer's smart phones and our servers. My next step will be to reach out to the carriers themselves, but I
Small today. As IPv6 becomes the default setting, that will change. CB figured
many of their Network Engineers are probably on the NANOG mailing list and this would be a great place to start.
Thanks in advance for your time and assistance.
Sincerely,
