This read-only value reports the IP address of the neighboring device attached to the far end of this ATM interface, an address a network management station could use to send it SNMP messages on UDP port 161. An administrator reads this to discover the far-end management address either configured manually or learned dynamically through ILMI interaction with that neighbor, without needing separate documentation of the physical topology. For example, seeing a populated ausmInterfaceMyNeighborIpAddress confirms ILMI successfully learned the neighbor's management address, while a value of 0.0.0.0 would suggest neither manual configuration nor ILMI discovery has completed.
