Where can I find a list of MAC (ethernet) address assignments.
i.e. blocks of addresses were assigned to various companies.
for example 8:0:20:xx:xx:xx is most likely a Sun machine
00:c0:7b:xx:xx:xx is some form of ascend router.
I'm trying to track down someone who is using an IP address that
they should not be using and all I have is their MAC address
I can take my answer off line
