 Ethernet ·£Ä«µåÀÇ MAC adress ±¸Çϱâ

// Call CoCreateGuid. The last six bytes are equal to the MAC address of
// the Ethernet card. (Note that if you have more than one NIC in your
// computer, you'll get the MAC address of one of them, but you can't
// easily control which one.)

// Sneeky... I like it! This will work quite neatly on systems without an
// ethernet card as well. AFAIK this part of the GUID is constant even if you
// only have PPP or even no-networking installed. A useful source of machine
// unique IDs...makes you wonder what the fuss about the PIII ID was about(not
// that I think it's a good idea ;)
