I found Jay Jays mac address generator where he sets the last two bits on the first byte to 01 which means that the mac address is UNICAST and locally administered. I’m just curious of what the consequences could be (if the device is used behind a local router) if these are not set to this. Could the router reject the dhcp request for instance?
