What is ipNetToMediaNetAddress?
The IP address that corresponds to the physical address in this ARP-table entry. Paired with ipNetToMediaPhysAddress, this row is what a security team pulls when investigating a suspected duplicate-IP or ARP-spoofing incident, since it's the gateway's own live view of which MAC currently claims a given IP. Example: querying ipNetToMediaNetAddress for a known server's IP and finding it now maps to an unfamiliar MAC is direct evidence of an ARP-spoofing attempt on that segment.
