Re: Using ARP to map a network

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

In WLAN Sniffing mode, you need not be at the L2 but can sniff the traffic which flows in the air at L2.  You will have 
no clue about the IP range.  All you can do is, send a RARP to know IP addresses.  I just seeking some automated RARP 
tool, which can send queries to know IP addresses, as a script or whatever.

Thanks..!
