How do ipv6-only customers reach ipv4 hosts? Wouldn't some 6to4 gateway count as CGN? I've had this problem in the past with Vodafone, sometimes their AFTR (?) would go down but all ipv6 enabled hosts were still reachable. Only the ipv4 internet was unreachable. It took months for me to find that out, and I still don't know any workaround in case that happens again. |

T-Mobile is running IPv6-only using 464 which is vulnerable to AFTR problems like you saw.
