Good day! Has anyone seen such ARP packets? I am a bit curious, because we have no strange hardware that will set the target hardware address in the who-has ARP packet. Are there any attacks that using such packets? ----- 15:29:59.908901 arp who-has the-host-in-question (4:c0:40:1:e0:df) tell the-requester 15:30:00.911228 arp who-has the-host-in-question (57:43:50:10:40:0) tell the-requester 15:30:01.912045 arp who-has the-host-in-question (2e:2f:30:31:32:33) tell the-requester 15:30:02.913314 arp who-has the-host-in-question (2e:2f:30:31:32:33) tell the-requester 15:30:03.915013 arp who-has the-host-in-question (2e:2f:30:31:32:33) tell the-requester 15:30:04.915854 arp who-has the-host-in-question (2e:2f:30:31:32:33) tell the-requester 15:30:25.962925 arp who-has the-host-in-question (2e:2f:30:31:32:33) tell the-requester 15:30:26.966171 arp who-has the-host-in-question (2e:2f:30:31:32:33) tell the-requester 15:30:26.991402 arp reply the-host-in-question is-at 0:d:88:e6:db:dc 15:31:01.025945 arp who-has the-host-in-question (7:1c:c3:0:72:8c) tell the-requester 15:31:01.040650 arp reply the-host-in-question is-at 0:d:88:e6:db:dc 15:32:01.308911 arp who-has the-host-in-question (4:f9:50:10:ff:ff) tell the-requester 15:32:01.319515 arp reply the-host-in-question is-at 0:d:88:e6:db:dc 15:33:01.448065 arp who-has the-host-in-question (0:b0:2:0:25:f) tell the-requester 15:33:02.448924 arp who-has the-host-in-question (2e:2f:30:31:32:33) tell the-requester 15:33:02.573582 arp reply the-host-in-question is-at 0:d:88:e6:db:dc 15:34:00.568785 arp who-has the-host-in-question (0:b0:2:0:25:f) tell the-requester 15:34:01.569537 arp who-has the-host-in-question (2e:2f:30:31:32:33) tell the-requester 15:34:01.625362 arp reply the-host-in-question is-at 0:d:88:e6:db:dc 15:35:00.836038 arp who-has the-host-in-question (0:0:1f:0:a:c7) tell the-requester 15:35:00.956094 arp reply the-host-in-question is-at 0:d:88:e6:db:dc 15:36:12.412916 arp who-has the-host-in-question (94:eb:ed:1a:71:fb) tell the-requester 15:36:12.423227 arp reply the-host-in-question is-at 0:d:88:e6:db:dc ----- 'the-host-in-question' and 'the-requester' are, of course, IP addresses.
