• T-Mobile embraced the concept of IPv6-only, since dual-stack required IPv4 that was not available • NAT64 / DNS64 was a good solution that did not require IPv4 on each client, but some applications failed to work on IPv6-only networks. It is not acceptable to break Skype or Netflix, applications that require IPv4

T-Mobile IPv6 users come from a very large IP range. Blocking this IP range, even to try and stop an LTA such as the "dog and rapper vandal", will cause collateral damage. Note that not all T-Mobile addresses are IPv6 addresses: T-Mobile IPv4 addresses can be treated like any other mobile provider IP address. T-Mobile defaults to IPv6 on iOS devices, and I have found that for certain internet destinations in Safari, connections will only be successful if a NAT64 mapped version of the IPv4 address is used.My question is: what are the IPv6 NAT64 prefixes within T-Mobile's network? Is there just one or are T-Mobile in the United States was running out of IPv4 addresses and needed an IPv6 transition strategy. Their solution was 464XLAT and IPv6-only. 464XLAT is an IPv6 transition technology documented in RFC 6877, which builds on previous technologies such as NAT64 and DNS64. The problem for T-Mobile with just using NAT64 and DNS64 was that […] The question is: is this a fundamental limitation of IPv6 only, or is this a problem with T-Mobile's network? When I try to ping an IPv4-only address (either the address of our VPN server, or Google's public DNS at 8.8.8.8) while connected to the T-Mobile IPv6 only network, it works — T-Mobile seems to map the IPv4 address, presumably using T-Mobile's IPv6 service is an IPv6-only service that uses 464XLAT / RFC6877 in the network to connect IPv6 mobile users with IPv4 content. We believe that the majority of the bandwidth consumed by IPv6 subscribers will be native end-to-end IPv6 without any translation required by the end of 2012 as major content providers like Google, Yahoo, Facebook, Microsoft, and many others have May 17, 2011 · T-Mobile's LTE network is a pure IPv6. Apple has been on a mission to eliminate IPv4, and recently disabled translation of IPv4 literal addresses. This affected users on T-Mobile primarily because T-Mobile does not run a dual-stack IPv4/IPv6 network. Apple's recommendation is that app developers stop using IPv4 literals.

IPv6 is used around 70% of the time for Android and over 30% of the time for iPhones, up 10% each from May. We have also seen T-Mobile start to deploy IPv6 to iOS devices as well in a dual-stacked configuration.

APN Protocol: IPv4/IPv6; APN Roaming Protocol: IPv4/IPv6; iPhone (iOS) Like Android, you can setup your iPhone manually so that it can work on a data network. Here is how you can setup your iPhone on T-Mobile’s data network in the US. Go to ‘Settings’. Tap ‘General’. Tap Network Cellular data. Enter the following settings For example, T-Mobile USA has more than 90% of its traffic going over IPv6, with Verizon Wireless close behind at 82.25%. Comcast and AT&T have its networks at 63% and 65%, respectively, according Quickly program your remote, setup email, connect dsl/internet gateways and modems, connect to WiFi, setup parental controls, and solve U-verse TV error messages.

T-Mobile USA started their IPv6 transition in 2010 with DNS64/NAT64 as a test network. They discovered issues on DNS64 with IPv4 literals. Cameron co-authored a new standard, 464XLAT, to solve this issue and successfully deployed it in T-Mobile USA's commercial mobile network.

Mobile IPv6 benefits from the IPv6 protocol itself; for example, Mobile IPv6 uses IPv6 option headers (routing, destination, and mobility) and benefits from the use of neighbor discovery. Mobile IPv6 provides optimized routing, which helps avoid triangular routing. T-Mobile International AG is among the operators that are already testing IPv6 phones in their networks, said Lutz Schade, an executive vice president with the German operator.
