Subject: Caching a sniffer


While there's no way to be sure-sure ... you can get into your
local LAN segment and send ICMP(/whatever) requests to the
correct L3 address with the wrong L2 address and see if you
get a response; this will show you if hosts/devices are listening 
promiscuously (which makes for a good starting point).
