yeah. There are about 500-600 machines in this place, I say this because
these are the registered machines. What about those not registered?
there is one thing that bother them is that when we tried to use arp it
seems that they are about 100 machines with the same mac address.
Wonder could this be the the machines here have been poisoned?

The biggest problem with your question lies in topology restrictions.
Unless you have a host system in the broadcast domain (aka subnet) of
the host ip in question, all your arp responses will be that of the
gateway enroute to the end host.
You'll get -very- skewed results if you're trying to map say...1000
machines (most of which live on different subnets) and see nothing but
the MAC of your router as the resolved address.
For something enterprise wide, you will need to look at scripting a
arp cache harvesting mechanism. This can report back the REAL mac to
ip mapping for the host system.
Contact me offline for more information on how to accomplish this.

Hi list,
Need help. Is there any open source tools linux or windows, that
when given a MAC address, the list(s) of IP address can be obtained?
