RE: IP to MAC mapping

["Seth Connolly" <sethc () firstcash com>]

I use GFI LANguard Network Security Scanner 3.0 to scan my IP ranges.  It
will give me things like the computer name, IP address, MAC address,
username, OS, shares, open ports, Security Alerts, drives, processes,
services, etc... (and it's free)

For extra money, you can do reports, comparisons, etc.. I think version 2.0
is totally free (you'd have to search for it though), and you can do HTML
reports, which you could write a script to get the MAC address out of the
HTML and compare it to a database.. but that may be the long way around.

It may not be exactly what you're looking for..  but here it is anyway:

Hi,

we are currently looking into illegal usage of a protected network. We are
managing a class C network, and we would like to be able to detect illegal
usage of the network by finding the MAC address of the ip address used and
then checking it against a database.

Now I would like to find a software or a perl scrip that would do the work.
(The budget that we have is 0$, so freeware is likely to be the solution)

I have tried doing searches using google without any luck. If anyone uses
such software, please tell me which one, and where I can find it.

Thanks,
