Could we simply turn off IPv4 on ESP32/S2 and what would happen?
This contribution focuses on embedded IoT devices in IPv6 networks, specifically to microcontrollers with lwIP network stack.
The article elaborates on the following topics:
* What IPv6 brings to IoT?
* IPv6 modes supported in lwIP (SLAAC, DHCPv6) and how to use them.
* Network interfaces in lwIP and their esp-idf abstraction with regard to IPv6 configuration.
* Comparing resources on ESP32 with IPv4 only, IPv6 only and dual stack configuration.
* Demo: ESP32 running in QEMU with virtual IPv6 only network, connecting to IPv4 broker.
