B4R Question Ethernet-shield MAC address

    I'd like to know if there is a kind of rule to compose MAC address for Ethernet shield, when I assign random MAC, sometimes I can not connect to network and I have to try again before I get it work!
    As I know, any networking device should have MAC address by manufacturer, why should we assign MAC to this shield anyway and how can we get it's original MAC.

    There is no original MAC with the ethernet shield.

    I don't think that there are any special rules related to the 6 bytes that make the MAC address.
