Hello guys. i have ethernet shield but there is no the MAC address anywhere... how can i find it ?


Just make one up- as long as it's unique on the lan-side you'll be fine.

Most people use DEADBEEFFEED- easy to remember.  8)

byte mac[] = { 0xDE, 0xAD, 0xBE, 0xEF, 0xFE, 0xEE };

simply put that in the line in the arduino IDE example "Web server" and have fun!
