Is it possible to print client IP or MAC address from Arduino WiFi web server? For a school project I want to make a little project with the Arduino Uno. I want to make a project that does something when a client connects to the WiFi shield.

My first thought was to print out the IP address or MAC address of the client but I can't find the codes for it. It is possible for me to print out the host IP? I have searched on the web for some time but only the ethernet shield will appear. Is my question even possible with an WiFi shield or do I have to get an ethernet shield?

Kind regards.
***** Assuming it is an ESP8266 based WI-FI shield: *****

Wifi shield > PC

Open serial monitor. Baud rate 155200. Also check COM ports.

Test AT commands by typing AT.

If it responds OK, you're good.

Type AT+CIFSR for IP adress.
