Sniffer or a similar tool will get you a list of MAC addresses.

Just to give you some additional info on this:

- The network is made up of only Hubs, so there's no switch to get the
MAC addresses info from.

- I can't know how many machines are connected to the network because
there are several 'self-implemented' "departmental networks" because
some users just decided to get a hub, and use it to connect several
machines to the main network.

This is a crapy network, with ~100 machines, and no organization. I have
to try to solve the most critical problems, and then build a real
network step by step, but I can't start my job because the guy that pays
the bills decided that the first thing to be done is find out ALL the
machines that are connected to the network.

I thought there could be a tool to find out what are the MAC addresses
from all the machines currently connected to a LAN, and then, from that
list of MAC addresses try to find out what's the IP of each machine. I
know there might be some machines that aren't running TCP/IP, but I'll
have to consider those as marginal cases.

All help is welcome.

Dear network gurus,
�
My boss wants me to be able to find out all the machines that are
connected to our LAN, even if they are using a different IP range than
our official one. Is there any way to achieve this?

Thanks in advance,
