Re: [uug] Network scanning utility

[Richard Miller]

We wanted to scan for MAC addresses at work because all of the computer 
are registered in our inventory by MAC address.  A few users had 
changed their computer names and we needed a way to identify the 
machines.

Right, and the reason is because a router will change the MAC address 
of
a network packet to its own address before forwarding it on to a
different network.

So I don't think it is possible to get the MAC address of computers not
in your network.  Just out of curiosity, what would you do with these
MAC addresses anyways?
