IPv6 Support? #2521

mwuertinger · 2018-04-22T11:50:43Z

The Internet Protocol version 6 was designed 20 years ago. Unfortunately many devices (including virtually all IoT devices) still do not support it. IPv4 addresses are getting extremely scarce these days and many ISPs no longer allocate public IPv4 addresses for their customers (Carrier grade NAT) which is already causing connectivity issues for many people including myself. Therefore we should all strive for 100% IPv6 support.

Would it be possible to implement IPv6 on Sonoff devices or is there anything in particular that stands in the way?

Leseratte10 · 2018-04-22T12:05:24Z

Last I checked, the upstream libraries didn't support IPv6 yet: esp8266/Arduino#638
I found this: espressif/arduino-esp32#1261, but this doesn't apply to the ESP8266. And it seems to be in active development and not completely ready for release. When this is finished (and merged into esp8266/Arduino), IPv6 can be used in Tasmota.

Check again esp8266/Arduino#638

akram · 2020-01-15T10:22:10Z

Ardui core now supports IPv6 : esp8266/Arduino#5136

can we re-open thins one ?

ascillato · 2020-01-15T11:32:29Z

can we re-open thins one ?

No because it is already implemented in Tasmota. You have to compile by yourself enabling IPV6 support in platformio.ini

If you need further assistant, please, do not hesitate on asking on the Support Chat. Thanks.

akram · 2020-01-17T13:10:35Z

Hi @ascillato , thank you for your quick answer.
I had a look at platformio.ini and I didn't find a self exaplanatory commented out parameter to enable it.
That would be good if you could tell which one it is?

akram · 2020-01-17T13:14:07Z

my bad , it looks like related to this:

; lwIP 1.4

;                            -DPIO_FRAMEWORK_ARDUINO_LWIP2_IPV6_HIGHER_BANDWIDTH

ascillato · 2020-01-17T13:15:36Z

yes, exactly.

If you need help on using those, you can use the support chat if you want.

ascillato · 2020-01-17T13:17:32Z

Anyway, as the comment explains, it is experimental because the support is on the Arduino Core. You should use the stage core that have several fixes for that, but still experimental.

Use it, if you really need ipv6 in your local network. ipv4 for a local network is reliable and works for all usecases.

freifunkerffm · 2020-09-23T14:23:42Z

Hello,
from the post above I understand that TASMOTA is supporting IPV6 in general.
I have already a working platformio-core setup where I can compile TASMOTA with different features with success!
But I fail with IPV6 :-/
In platformio.ini I have set:
; lwIP 2 - Higher Bandwidth IPv6 (use ONLY if you need IPv6, experimental!)
-DPIO_FRAMEWORK_ARDUINO_LWIP2_IPV6_HIGHER_BANDWIDTH

But it fails to work on a NODEMCU V3 board.
The serial-log from the device shows:

Has anyone compiled TASMOTA with IPV6 and can give dedicated hints what settings in platformio.iniare necessary?
I am also curious if ESP-8266 is then turned into a single IPV6 stack or into a dual stack (IP4/IP6) device?

Kai

altelch · 2020-09-23T16:18:38Z

Hi, no, you didn't miss a build-parameter. Just did a build on my own including #pragma message to see if #ifdef LWIP_IPV6 is set. And yes, it is but the startup seems to be messed up. Normaly IPv6 was DualStack and you should get at least an IPv4 address but now there is no address at all. I have to admit that this code was implemented in october 2019 and since then I didn't check this part. There where a lot of changes (including ESP32 support) since then. First step is to check https://github.com/esp8266/Arduino/tree/master/libraries/ESP8266WiFi/examples/IPv6/IPv6.ino what is the example code of the arduino framework. If this works it needs some digging into the current tasmota code...can't promise to find some time, soon. Greetings, Altelch. LWIP_IPV6 Am 23.09.2020 um 16:24 schrieb freifunkerffm:

Hi,

IPv6 works with 8.5.0. Somehow platformio.ini isn't evaluated after changing DPIO_FRAMEWORK_ARDUINO_LWIP2_HIGHER_BANDWIDTH_LOW_FLASH to DPIO_FRAMEWORK_ARDUINO_LWIP2_IPV6_HIGHER_BANDWIDTH

Did also put a
#pragma message ("IPv6 compile time enabled!")
into support_wifi.ino in WifiBegin after #ifdef LWIP_IPv6 to see if this branch is compiled. After a few trials gitpod started to compile the whole project again and this time I got my above message during compile. The firmare works as expected:
00:00:05 WIF: Got IPv6 global address xxxx:xxxx:150:5ecf:7fff:fe88:xxxx

Greetings,

       Heiko.

freifunkerffm · 2020-09-24T18:39:15Z

Hello Heiko,
I tested it again with a freschly checked out TASMOTA : git clone https://github.com/arendst/Tasmota.git
I changed platformio.ini like that:
;-DPIO_FRAMEWORK_ARDUINO_LWIP3_HIGHER_BANDWIDTH_LOW_FLASH
-DPIO_FRAMEWORK_ARDUINO_LWIP2_IPV6_HIGHER_BANDWIDTH
and used no user_config_override.h
But compiled it with platformio and not with gitpod.
I also added your pragma message in the support_wifi.ino.
That is visible in the build log:

Hi all,
I gave it another go, this time I compliled the tasmota Development Branch: https://gitpod.io#https://github.com/arendst/Tasmota/tree/development via gitpod.
Just changed one line in platformio.ini , I replaced:
DPIO_FRAMEWORK_ARDUINO_LWIP2_HIGHER_BANDWIDTH_LOW_FLASH
with
DPIO_FRAMEWORK_ARDUINO_LWIP2_IPV6_HIGHER_BANDWIDTH

And compiled a pure tasmota with: "platformio run -e tasmota"
Used tasmotizer to flash, and got again something I have already seen:

So sorry I am not able to confirm that IPV6 is working on a TASMOTA device.

XenGi · 2022-02-09T20:58:01Z

Another year went by and my tasmota devices still has no IPv6 support by default. It is still needed to compile tasmota by hand to enable that feature?

barbudor · 2022-02-09T22:14:12Z

AFAIK, even by compiling with either hand or feet you won't get IPv6 running on Tasmota.
It's definitively not designed for it (all internal IP addresses representation are on 4 bytes)
And there is not much need to run a home automation system on an IPV6 network.

Raja4Shekar · 2022-02-23T01:52:39Z

There are so many places where public ipv4 address is not provided by ISP due to the use of CGNAT, so in those circumstances, ipv6 is too much useful. So many people will get benefited if Tasmota Support ipv6. Especially who are ardent in using Tasmota

Not sure if this link helps anyway

redhat421 · 2022-02-23T03:57:36Z

I run Tasmota on a S31 w/ IPv6 enabled. It works.

I give it an address via SLAAC.
I have noted that if the router isn't handing out Router Advertisements, the device will hang for ~2 mins then come up with an IPv4 address only, so look out for that.

Thanks!

XenGi · 2022-02-23T17:02:03Z

Honestly you don't need to fish for NAT or IPv4 shortage reasons to support IPv6. It's the current version of the internet protocol and it is at this point over 20 years old. By not enabling it by default your basically building legacy systems.

So I think this ticket should be reopened. IPv6 support is still not enabled by default. I would rather use something that lacks IPv4 support than something without IPv6.

RedBlackThunder · 2022-02-23T17:51:17Z

I would like an IPv6-only option even more than dual stack.

s-hadinger · 2022-02-23T17:57:12Z

There is no plan for IPv6-only option in Tasmota. Why would you even want to not support IPv4 ?

XenGi · 2022-02-23T18:30:00Z

There is no plan for IPv6-only option in Tasmota. Why would you even want to not support IPv4 ?

Let me rephrase:
There is no plan for car only roads. Why would you even want to not support coaches.

IPv4 should be nothing more then a fallback. A widely used one for now. But hopefully things will finally change.

kroon040 · 2022-07-16T20:41:48Z

Will there be ipv6 full support? Dual stack, with dhcpv6 and slaac? It's availiable in the esp-idf, so hopefullt soon in tasmota

sfromis · 2022-07-16T20:45:51Z

As Tasmota is designed for internal networks, not the big bad Internet, the "real benefit" of IPv6 would be marginal at best. I certainly have no scarcity of IP addresses within the reserved ranges.

kroon040 · 2022-12-13T21:57:45Z

Leseratte10 · 2022-12-13T22:04:04Z

I don't think support for DHCPv6 is that important. Sure it should be implemented eventually, but I bet a fairly large amount of networks is going to work without that, too, as Android is also not supporting DHCPv6 due to a stupid design choice.

Though, it'd be cool to get DNS AAAA requests to work so you could for example connect to an IPv6-only MQTT broker or syslog server without having to hardcode an IP.

EDIT: Haven't been able to test the current builds yet, but thanks for all your work on updating Tasmota for IPv6!

EDIT 2: Has connecting to an IPv6-only OTA update server and/or an IPv6-only syslog server been tested yet? If not then I'll try doing that when I finally get to flashing that beta onto one of my devices.

EDIT 3: What about multiple prefixes, like one global prefix and a ULA? Has that been tested?

s-hadinger · 2022-12-14T08:40:40Z

IPv6 only OTA doesn't work for now because the safeboot partition doesn't support IPv6. We haven't decided yet if we include IPv6 in safeboot nor have identified the code size increase.

Syslog on IPv6 address should work but was not tested.

I doubt multiple prefixes nor ULA are supported by esp-idf. Anyways the underlying lib has a hard limit for 3 IPv6 addresses per interface: 1/ Local-link 2/ Global 3/ ???.

@s-hadinger , compilation for tasmota32 is ok, but for the tastmoa32solo1 it fails

I suppose that it's because the Arduino/esp-idf lib is different from the Esp32 and does not yet include the IPv6 code. @Jason2866

As expected, since solo1 is an extra different framework. There is no IPv6 version (yet).

Jason2866 · 2022-12-14T10:18:35Z

@kroon040
You can try with solo1 now. To use the solo1 you have to add in platformio_override.ini

platform_packages = framework-arduino-solo1 @ https://github.com/Jason2866/esp32-arduino-lib-builder/releases/download/1092/framework-arduinoespressif32-solo1-release_v4.4-a0113c7bfe.zip

EDIT: Correct file where to place.

kroon040 · 2022-12-14T10:40:42Z

I added this , but it fails . Must there be something more and define?

I have this now in user_config_override.h

#define USE_IPV6
platform_packages = framework-arduino-solo1 @ https://github.com/Jason2866/esp32-arduino-lib-builder/releases/download/1092/framework-arduinoespressif32-solo1-release_v4.4-a0113c7bfe.zip

Jason2866 · 2022-12-14T12:28:43Z

@kroon040 The framework stuff needs to go here
You can use this as platformio_override.ini just dl and rename.
Tested solo1 does compile successfull
Sorry i gave you a false info!

kroon040 · 2022-12-14T13:44:29Z

It compiles and the ipv6 works also now on de esp32-solo1

Jason2866 · 2022-12-14T17:03:49Z

Latest development has now in platformio_override_sample.ini all IPv6 framework versions. Just uncomment and enable IPv6 with #define USE_IPV6 in user_config_override.h
The frameworks should work with and without enabled IPv6.

s-hadinger · 2022-12-15T21:46:41Z

Hi all, IPv6 is progressing well. I have a working version of Ping for IPv6 (ICMP6) and a version of DNS resolver for IPv6 addresses (AAAA records) with the possibility to choose whether v4 or v6 has priority. I still have an issue with Ethernet dns resolver so it's not quite ready for release.

Stay tuned

kroon040 · 2022-12-16T14:40:35Z

@Jason2866
For the ESP8266, this is not yet in the platform_override.ini? This I see only in the platform.ini

Jason2866 · 2022-12-16T16:28:13Z

@kroon040 For esp8266 there is no different framework needed. The used one is IPv6 ready. Just needs to be enabled with
-DPIO_FRAMEWORK_ARDUINO_LWIP2_IPV6_HIGHER_BANDWIDTH build option instead of
-DPIO_FRAMEWORK_ARDUINO_LWIP2_HIGHER_BANDWIDTH_LOW_FLASH

s-hadinger · 2022-12-17T09:11:27Z

With the latest PR, preliminary work for ipv6 is complete. Now dns works for AAAA records and ping works for ipv6 (ICMP6)

For DNS, in case of dual stack, ipv4 is prioritized unless you set SetOption149 1.

Please note that IPv6 only networks are not yet supported and yield to a crash after some time.

Please report any issue. I will also start a ipv6 page in the doc.

s-hadinger · 2022-12-17T10:17:52Z

For example, on a network with both v4 and v6 addresses:

ping www.wikipedia.org

11:19:18.467 MQT: stat/tasmota_B90B50/RESULT = {"Ping":"Done"}
11:19:19.534 MQT: tele/tasmota_B90B50/RESULT = {"Ping":{"www.wikipedia.org":{"Reachable":true,"IP":"185.15.58.224","Success":1,"Timeout":0,"MinTime":19,"MaxTime":19,"AvgTime":19}}}

SetOption149 1
ping www.wikipedia.org

11:20:04.673 MQT: stat/tasmota_B90B50/RESULT = {"Ping":"Done"}
11:20:05.786 MQT: tele/tasmota_B90B50/RESULT = {"Ping":{"www.wikipedia.org":{"Reachable":true,"IP":"2a02:ec80:600:ed1a::1","Success":1,"Timeout":0,"MinTime":13,"MaxTime":13,"AvgTime":13}}}

On the first call www.wikipia.org resolves to 185.15.58.224. With SetOption149 1, www.wikipedia.org resolves to 2a02:ec80:600:ed1a::1

Jason2866 · 2022-12-17T15:46:10Z

For all ESP32x builds IPv6 support is now enabled with latest commit (Core 2.0.5.4).
You can use the latest precompiled development builds.

s-hadinger · 2022-12-17T21:46:01Z

There is now a documentation page dedicated to IPv6: https://tasmota.github.io/docs/IPv6/

s-hadinger · 2022-12-17T21:46:40Z

Closing this issue for now. Please reopen a new one if a problem is discovered.

kroon040 · 2022-12-28T13:55:25Z

Hi,

I took the latest development todat and tried IPv6 with the esp8266. Changed the platformio.ini and add in the user_config_override.h

#define USE_IPV6

When compiling I get this error?

The location of the caret makes me suspect that the blank after #define may not be a "real" blank 0x20 but some other whitespace char, maybe a non-breaking space?

kroon040 · 2022-12-28T14:51:52Z

Yes that was the problem, now it compiles .

kroon040 · 2022-12-28T15:28:04Z

Don't I have to put it any more for the esp8266 in the user_config_override.h? It looks like also for the esp8266 its enabled by default??? It compiles but get these warnings.

s-hadinger · 2022-12-28T19:14:33Z

We have enabled RDNSS on esp32 to discover DNS servers on Ipv6. This is not enabled on esp8266 and would require a specific build of esp-idf. I was too lazy to try. If you are interested though
