yes. When there is a packet, directed
to your IP but to a different MAC address then it is pretty clear there
is someone using your IP.
usually this is done on Broadcast packets
so you can detect it also in switched networks. Basically ARP is used.
i didn't understand...
i configured emac on my microcontroller to filter ethernet packets, so, only packets for my macaddress OR broadcast ethernet packets are forwarded to microcontroller.
So, packets with different mac and different IP are not received, and broadcast ethernet packets have FFFFFFFFFF as mac address (i.e. arp packets), so i cannot detect ip conflict....
can you explain me your idea??
thanks
