Re: Using ARP to map a network

["planz" <planz235 () hotmail com>]

I am also searching for a similar tool or perl script, which can do a RARP to find IP addresses.  Currently I am doing 
this on WLAN.  I am able to sniff MAC addresses of different WLAN clients and Access Points.  All I have is a list of 
MAC addrresses. From here, I want to map the network. I am tired of googled it. Some one please help...!
