Does ESP32 support IPV6?

[MMB1999]

Hello All
I have a husarnet network that contain Three element. One of them is a PC with windows OS and the others are two ESP32 boards.
One of the ESP32 acts as a server for PC and other ESP32. So the architecture is:
1.ESP32 Server
2.ESP32 Client
3.PC client
When I send request from PC to ESP32(Server) using IPV6 the ESP32 operate well and responses to requests. for example PC send request http://[fc94:xxxx:xxxx:xxxx:xxxx:xxxx:xxxx:aeeb]/TurnOnGPIO2
and ESP32(Server) Turns the GPIO2 on.
But when I try to do somthing similar with ESP32(Clinet) the request-response process is broken and the ESP32(Server) does not responses to requests. Notice that I am using HTTPClient.h library.
In your opinion what is go wrong?
Does ESP32 Support IPV6?

Could you please show an example of use IPV6 request in ESP32?
Please help me

Hi @MMB1999, I’m not sure whether HTTPClient.h library supports IPv6.

In my own projects I prefer to use AsyncTCP library instead, here a examples:

1. Making a HTTP Client request: https://github.com/DominikN/ESP32-to-ESP32/blob/master/src/ESP32-to-ESP32.ino#L177

2. A basic HTTP server example: https://github.com/husarnet/esp32-internet-ota

Two examples above are using Husarnet.

I hope you will find that helpful.

Best,
Dominik
