Re: Re : MAC Address to IP Address conversion

Another trick that works to make sure you get everything is to first clear the arp cache (clear arp-cache) and then ping the broadcast address (either the all zeroes broadcast, or if you just want one net, then ping that network's broadcast, i.e. if your net is 209.149.135.0/24, then ping 209.149.135.255).  Every device that falls in that range (barring any subnet masking mistakes), and if all machines are powered on will answer the router's pings.  Now do your "show arp", you'll get a very accurate mac to ip address table.

Hello All,

I am looking for some sniffer software that could show me a list of MAC Address to IP Address mapping of my netwo! rk.
I checked with the trial copies of CNAPro and Sniffer PRO would could not find the functionality.
Can anyone suggest.




Thanks & Regards
Amit
