In my university network, IP numbers must match a
previously registered MAC address, otherwise the IP
number is blocked. So our group has a list of IP
numbers, that each only work with a specific MAC

When shifting around computers and IP addresses, it
is easier to fake the MAC address to what I need,
than to start a procedure with the computer center
to change the MAC address of a certain IP number.

I manage to do this easily on my FreeBSD PCs.

However, my colleagues are suprised and ask me how
to do this on their MS-Windows systems.....
