What is ipliDestNetUnknown?
DestNetUnknown is a read-only Counter32 counting the number of Destination Network Unknown report frames recorded for this IP-to-IP conversation; a value of 4294967294 means the count is unknown rather than a genuine zero. This counter matters to an admin because it isolates a router reporting it has never even heard of the destination network, letting them see that specific condition trending up without having to sift through every ICMP message the host or pair exchanged. If DestNetUnknown for the pair 10.4.12.30 and 198.51.100.7 starts climbing while other ICMP counters in the same row stay flat, that isolated rise points specifically at a router reporting it has never even heard of the destination network rather than a general ICMP flood.
