Исправление Turbid, (текущая версия) :

итак, хост 0.10 со вчерашнего вечера выключен, но arp с 0.5:

nas:~$ ip neigh show 192.168.0.10
192.168.0.10 dev br0 lladdr 2e:fa:d1:f3:9f:f7 STALE

далее пингуем:

24 packets transmitted, 0 received, +21 errors, 100% packet loss, time 23005ms
pipe 4

и смотрим снова arp-таблицу: 

nas:~$ ip neigh show 192.168.0.10
192.168.0.10 dev br0  FAILED

Есть мнение, что пока снова не включу-выключу 0.10 - эксперимент не повторю.

Сегодня попробую поиграться с tcpdump, спасибо за наводки.

p.s. Есть идеи откуда левые ip в arp-таблице?
