**W5500 pins are defined in the platformio.ini file.

IMPORTANT NOTE: The interrupt pin MUST be used.

Example Serial output

ETH Started
hostname: ESP32 123
mac: 00:00:00:00:00:00
ETH Connected
ETH got IP: 192.167.0.152

Example of access in the browser

Hostname display

As defined in ETH.setHostname(hostnameBoard); (line 41, main.cpp), the ESP32 has the hostname "ESP32 123". On the router of the network to which the ESP32 is connected, you can see this hostname:
