I recently set up my APN to use IPV6 instead of IPV4. However, my download speeds are around 8 mb rather than 18 mb on IPV4 mobile network.
Is there a reason for this? Can anyone else confirm that this is happening to them?
I got similar results. I just switched back.

How were you testing? Was it via an IPv4 or IPv6 host?

That's the thing, I'm not sure how to do a test on an IPV6 host. I am assuming the Comcast server here in Boulder has IPV6 because my Internet does. When tested on he tmobile server in Denver I got consistent but lower speeds.
I've noticed the IPv6 APN maybe some 10–20% slower, but not 60%!
Consider making a detailed post on how you tested, and add a post to T-Mobile's IPv6 mailing list so some of us can try to reproduce?

I have applied to the group. Whenever I get accepted I will post a detailed response.
Thanks.
I switched to IPv6, and my speeds are better than with the standard T-mo data settings.

I have been able to tether over HSPA+ (IPv4) since forever no problem. But recently, LTE service has been expanding to where I am.
In order to connect to an LTE tower, I must use IPv6 APN fast.t-mobile.com
But tethering doesn't work on IPv6 connections.
Has anyone been able to figure out a way around this dilemma?
I use IPV4 on LTE, I don't understand why you "have to" use IPV6?

Could you tell me which APN you are using? I could not sign on to LTE using EPC V4 or V6 or V4/V6, nor fast on V4.
Could you share a screen shot of your APN settings?

I'm having the same issue. I had no idea / am not sure that it is related to the IP version one uses. There is however an interesting document in the nexus lte forums with exactly the same problem and more importantly, a solution. The discussion is here: http://forum.xda-developers.com/showthread.php?t=2044870 with the solution posted on page 2 (my guess is we'd have to adapt it for t-mobile specific apn settings) the script code is here for quicker / shorter reference http://forum.xda-developers.com/showpost.php?p=34662473&postcount=11.
Update! since posting this, I tried under the apn settings for fast.tmobile.com changing the ip version from IPv4 to IPv4/IPv6. now it's letting me tether no problem I'm on the latest jedi master rom btw.
Has anyone found a way to get tethering to work while you have a VPN active? I tried openvpn with private tunnel and they don't allow for data to be sent to the phone when active.
I noticed our phone shipped with ipv6 only with clat. Crazy they are using us for a beta test. ipv6 with clat is ok but some apps still don't work. VPN at least with me, doesn't work.
I added ipv4 APN and VPN connects but the tethering passes no data when active.
I'm wondering if the stock tethering app adds a special route and if a different tethering app or vpn client can bypass it. I wish treve tethering worked.
I got treve to work using a vpn hider weeks ago but the speed was so slow it was taking 30 seconds to load a webpage, I just gave up and bought Pda-Net and haven't worried about it anymore. Even using Chrome spoofed my data racked up and got me flagged after a couple of weeks so I just broke down and paid for this.
How did you use vpn? And how did pda hide your data better?
you have to
1) add the word admin after supl, in the "APN TYPE"
2) also under your "APN Protocol" choose either ipv4 or ipv4/ipv6
there is a thread a few days back with pictures
depending on your rom, you may have to create a "new" apn file, there is a thread for that too

This is exactly I what I had to do on stock. Create a new apn, because I want able to edit the tmobile apn. Though I added word admin first in the "APN TYPE"

Using PDA-Net / Foxfi paid under data usage Foxfi shows 4.91kb used for the last 24 hour period when in reality I downloaded 2 full length movies tethered to my laptop as well as 7 hours tethered just browsing and whatnot. Thats at the default setting of level 1 hide tether usage, prior to switching to Foxfi I was using Chrome to spoof with an addon but it would show the actual usage just under that spoof and T-MO acted accordingly, granted they din't do anything until I was upto 30 or 40 gigs lol but still I was raising red flags with them. I'm sure I am an extreme example and most folks can just keep doing the Chrome spoofing and not buy Foxfi key.
Yeah I did that. It didn't help tethering vpn routing.

I have a T-Mobile G3 and I am unable to set my APN (a copy since the built-in one is not editable) to IPV4. If I do that, the phone does not connect to the mobile data network. Looking at the logs, I get this error:
D/MobileDataStateTracker(28614): default: Received state=DISCONNECTED, old=CONNECTING, reason=apnFailed
Setting IPV6 or IPV4/IPV6 will quickly connect.
I also found some references to 6to4 when connecting to the network. I didn't copy them, but I'll dig through to find them and update.
On other versions, can you use your APN with IPV4 only? If my theory is correct, the T-Mobile version being IPV6 only is breaking international roaming, which is a pretty big deal (most of the internet, let alone other operators, is not IPV6 enabled yet).
If anyone with a handset that isn't T-Mobile test this, it would be appreciated. Really need my international roaming and nobody is sure of the cause yet.

I'm having ipv4 issues and roaming issues as well. I called tmobile twice about it and they won't help me unless I'm in a foreign country having the data issue or after my data resets because I'm maxed on roaming data allowance

Im wondering why in aosp, why the apn setting using ipv4 T-Mobile US LTE......kills my data connection but T-Mobile US LTE IPv6 works.
Anything i can do on my end?
Kernel, rom related?
I'm not sure why this works (especially seeing both names resolve to the same two IP addresses) but I've found I can always get the IPv4 APN to work if I go in and edit the APN to fast.tmobile.com from fast.t-mobile.com.
Tethering still gives me problems when IPv6 is available so I am glad changing the APN destination works, even if I still can't explain it.
Weird....that did work. I'm actually getting faster download speeds under ipv4 compared to ipv6 lol
Here's another question, why can't I send or receive MMS on AOSP while on Wifi??
This note 5 is the first phone I have with AT&T that's getting a non-local (2600::380::....) IPv6 address from the cell tower. I wasn't getting ipv6 on my nexus 6 last week (same LTE network.)
Does anyone know if this was something that AT&T recently enabled, or if they are only doing router announcements to specific APN's and/or h/w?

From what I have read AT&T has started their plans for IPv6 since 2012 and started roughly mid 2014 rolling them out on the cellular network. They state the roll out will be slow, so it is possible they just turned it on by you. Is it possible also that it was not enabled on the Nexus 6 by default?

It's possible, but I'd think it would have to be on the carrier side if that was the case. With the nexus device, I was using the same firmware that everyone in Europe (and most of Asia) is using - and many of them were getting ipv6 numbers.
As well, my home wifi network (ipv6 dual stack) would result in an ipv6 address assigned to the handset.
Actually, to be more accurate, they were getting RA's. Android doesn't do DHCPv6 at all.
It's quite possible that AT&T just got around to turning it on in my area at the same time I switched phones, but that'd be an interesting coincidence. The more I think about this, the more I'm convinced it was related to the APN. I'm unable to check now, but I'm starting to wonder if the default APN for the nexus6 on AT&T blocks ipv6.

This guy states his was set for IPv4 by default instead of the normal ipv4/ipv6 setting.
Where are you seeing ipv6? In system settings >about device>status ? That looks like ipv4/ipv6 from your phone to att's internal network.
I did check ip6.me and that showed an ipv6 address, but couldn't be sure that was legit. ..

I'm using a third party program to check the IP addresses (one that specifically shows IPv6.) The same IP shows under settings->about->status.
The 2600:: address it's showing is a legit global IPv6 assignment, and android ONLY does SLAAC (not DHCPv6) so it must be seeing an ipv6 RA.
On the other hand, I can't ping it from the outside, so it appears that AT&T has some proxy between the phones and the "rest of the world." What I don't understand is why they'd be assigning proper global IPv6 addresses behind a proxy unless it's a stage in a larger rollout. (If they intended to keep things behind the proxy, they should be using fc00::/7 range addressing - or addresses starting with FD.)
For YOU, what ipv6 address are you seeing when wifi is turned off? If it starts with "260", it's part of AT&T's global block.

Yep, when not on WiFi, and just on data, IPv6 block starts with 2600. Interestingly, my IPv4 address starts 10.102 - so guessing that's internal IP. Not at all surprised that 2600 block is not accessible from "outside". That said, I'd be curious to see if two phones on the same ATT switch would be able to communicate with each other over the internal network? My inclination is that it's not at all possible, but...who knows?

I have a broadband modem (LTE) on my work machine, and when I connect to AT&T with that, i do NOT get an ipv6 address. Then again, it's using the older LTE apn of "broadband"
