I have some questions about the protocol ARP. One of my device send a "who has" arp packet to a other device. But the second device are in other subnet.
If I understand well a "who has" query is a broadcast, so it is normal that the second device don't reply the "who has" query since is not in the same subnet. is it? But why the first device send "who has" query?
Maybe I just don't understand how is working.
Here are the packet:
2.835165 wlan in arp who-has 192.168.10.40 tell 192.168.6.2
0x0000 ffff ffff ffff 0002 2d66 1bd2 0806 0001 ........-f......
0x0010 0800 0604 0001 0002 2d66 1bd2 c0a8 0602 ........-f......
0x0020 0000 0000 0000 c0a8 0a28 .........(
and no more reply after that.
