So if I grab a SIM card from T-Mobile or AT&T and put it in my iPhone, will I actually get an IPv6 address? What about Verizon and Sprint? This is actually a valid use case for me as a way to access stuff at home while I am remote.

For a single datapoint, my iPhone 6 running iOS 10 on AT&T does not seem to get an IPv6 address (it does on my home network, but not on AT&T LTE).

In my experience, for Verizon around the DC area, yes.

Yes. But since too many sites still are only reachable via IPv4, you either get also an IPv4 address (dual stack) or you get connectivity via NAT64/DNS64. The latter case means your phone cannot be reached from the outside via IPv4 (this is rarely needed on a phone, except when tethering a laptop, maybe).

  I am well aware of all that. I have been deploying IPv6 sites for a while now. I was more curious if there was any movement towards mobile devices getting IPv6. I am stuck with AT&T for a month longer or so and so I was wondering which carries actually support what I need. Last I checked AT&T did not, but that was over a year ago.

    VZW gives you an ipv6 address. I actually use a USB stick + vzw SIM for a backup internet connection via pfsense and it works well - ipv6 included.

    I have seen IPv6 addresses allocated to some ATT UEs. Not sure what was the percentage. Go here from the handset and check again? http://test-ipv6.com http://test-ipv6.com

My VZW phone has been IPv6 primarily for at least 3 years. (Portland OR market, 4G LTE) Edit: To clarify, the phone also has IPv4, but starts with IPv6 and falls back. Now if only I could get Comcast Business to support IPv6

  Comcast business supports ipv6 at least where i am, both for static and dynamic ips.

    Only barely. I supposedly get a /56 up here in Seattle, but prefix delegation will give me a /60 half the time and a "/59" half the time. The latter completely breaks every router I've thrown at it (pfsense, Cisco ASA, and tomatoUSB), and even with a supposedly-open support ticket I cannot get ahold of a Comcast Engineer for love nor money.

I've tried Verizon, AT&T, and T-Mobile. Verizon and T-Mobile give my phone IPv6 addresses while AT&T is IPv4 only. Only Verizon gives my tethered devices IPv6 addresses.

  I believe I have received a IPv6 address from a tethered LG G3 with T-Mobile. Have not tested with a tethered iPhone or paid attention in a while.

My AT&T iPhone gets a v4 address when I'm using my cellular data - but when I use my AT&T DSL connection, I get v6.
