Re: mac to ip address tools

[Chris Moody <chris () siliconhotrod com>]

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.
