I figured out how to configure a dual-stack IPv4/IPv6 "Access Point" for T-Mobile connectivity on my Samsung Galaxy Nexus, with stock Android 4.2.2. For some reason, when I visit http://myglobalip.com, I'm still getting an IPv4 address returned in addition to the IPv6 address.
Question: How do I configure the "Access Point" so that it only gets an IPv6 address, and not an IPv4 address?
My current IPv6 "Access Point" configuration looks like:
APN: epc.tmobile.com
Proxy: Not set
Port: Not set
Username: Not set
Password: Not set
Server: Not set
MMSC: Not set
MMS proxy: Not set
MMS port: Not set
MCC: 310
MNC: 260
Authentication type: Not set
APN type: Not set
APN protocol: IPv6
APN roaming protocol: IPv4
Bearer: Unspecified
IPv6
which hasn't helped at all. I'm still getting an IPv4 address as well. – Trevor Sullivan Apr 30 '13 at 2:14
