I wanted to ask a multi-part question. Does Comcast Cable Internet services record MAC Addresses of the Router behind the cable modem. I know they record it for the modem itself. But is there a way for the Modem/Comcast to relay and keep logs of the MAC ID of the Router itself? Then does a windows operating system Log the MAC ID of the Router when its connected to it? If so where do I locate and purge this? Please let me know all areas where it is Logged within the operating system. Thank you!
