Hi all

I know this might not be the best place but I am curious if there is something I can do about the MAC address to remain constant. I have seen such MAC addresses as below and they keep on changing esp. when the computer is starting up

DCDCDCDCDCDC
8C8C8C8C8C8C
CCCCCCCCCCCC

Not sure what I need to do about getting a real MAC address. I have two network cards, one which is on board for LAN use and another one I had to fit extra for my ISP. It is this extra PCIe card for which the MAC address keep on changing.

Please advise

Kind regards
