ARP question
Hi
I'm on switched LAN. I used Wireshark because I suspect somebody eavesdrops my communication between my computer and the gateway. I was looking at ARP requests in the form WHO HAS A TELL B. I found out that: 1) there are plenty of requests WHO HAS gateway_ip TELL some_node_ip with destination broadcast 2) there are a few request WHO HAS my_ip TELL some_node_ip with destination broadcast 3) there are plenty of requests WHO HAS some_node_ip with destination broadcast 4) there are requests that seems strange to me, namely: WHO HAS my_ip TELL gateway_ip with destination my_MAC_address So my question is: Why does gateway send ARP request directly to me (not using broadcast address)? |
