Since tmobile is using DNS64+NAT64 there are two things the maintainer can do: 1. if they're trying to connect to a hostname, just do a AAAA lookup and connect to that (DNS64 takes care of routing the connection through NAT64) 2. if they just have an IPv4 address to connect to, try to figure out the NAT64 prefix: http://www.ietf.org/mail-archive/web.../msg08666.html (specifically, option 6)
