Hi Espressif Systems Developer,

Right now, We are working on ESP32 IDF 2.0 SDK which is stable for application development purpose.

So, Now we have one requirement to move from IPV4 to IPV6 based communication.

So, Does anyone provide me some links and documents as well as let me know in which ESP32 SDK IPV6 fully support has been added?

If not added then what is your plan to add it fully and when?

Hi Loboris,

It will be great and helpful for us if you have already ported and checked LWIP stack for IPV6 support as we need to include IPV6 support now.

So, Please let me know your feedback on this ASAP.

I have no need for IPv6 at the moment. I know it is supported in lwip, but not much more.
Last information I have is

SLAAC is supported, DHCPv6 is not.

from Support for IPv6, including mixed IPv6/IPv4 operation

Hi Loboris,

Thanks for quick response.

Yes. I have checked that but not found much details.


Hi Espressif Systems Developer,

Would you please check and let me know that fully IPV6 functionality has been supported into current stable 2.1 ESP32 SDK?

Looking forward some suggestions or positive feedback from you guys w.r.t. IPV6 support.

Hi Ritesh,

Apart from DHCPV6, IPV6 support is present in ESP-IDF V2.1. The system will use SLAAC to configure an IPv6 address.

The firmware can call the tcpip_adapter_create_ip6_linklocal() function defined in tcpip_adapter.h to start the IPV6 address negotiation process.

The WiFi event system sends an event when an IPV6 address is confirmed:
http://esp-idf.readthedocs.io/en/v2.1/a ... sta-got-ip

The BSD sockets implementation in ESP-IDF supports IPV6 socket types, same as on any POSIX-compliant OS. IPV6 sockets can be used in the RFC-compliant dual-stack mode (ie by default if bind an IPV6 socket to ..._ADDR_ANY then it will receive both IPV4 & IPV6 connections).

Hi,

Thanks for Reply.

I will check it and let you know if any issue while using IPV6 support.

Meanwhile, would you please let me know that is there any specific configuration required for IPV6 support from SDK point of view?

No configuration changes are required to use IPV6.

I will check it and let you know result ASAP.

Hi Espressif Systems Developer,

When fully IPV6 including DHCPV6 will be included into ESP32-IDF RTOS SDK and also in which release version?
