receiver ARP reply from, not our client



Дано: Zyxel Keenetic city kn-1511

Прошивка 3.9.5

В сети помимо роутера есть еще несколько репитеров.

У одного из них MAC-адрес выглядит так: С0:С9:E3:6C:0E:5B

А дальше начинается самое интересное. В какой-то момент этот репитер отваливается.

В логах же наблюдаю такое (в хронологическом порядке):

received ARP reply from С2:С9:E3:6C:0E:5B, not our client

sending ACK of to С0:С9:E3:6C:0E:5B

DHCPREQUEST received (STATE_RENEWING) for from С0:С9:E3:6C:0E:5B


вопрос: что это за чудо такое на моменте received ARP reply, почему меняются первые два байта MAC-адреса?
