atNetAddress
Module: CHECKPOINT-MIB-2
OID (symbolic): CHECKPOINT-MIB-2::atNetAddress
OID (numeric): 1.3.6.1.2.1.3.1.1.3
Node type: OBJECT-TYPE
Type: IpAddress
Access: read-write
Description: The NetworkAddress (e.g., the IP address) corresponding to the media-dependent `physical' address.
What is atNetAddress?
The network-layer address, typically an IP address, that corresponds to the physical address in the same table row. Together with atPhysAddress this row is essentially an SNMP-visible ARP cache entry, so a mismatch between the IP an admin expects for a device and what's shown here is a quick way to spot ARP spoofing or a duplicate IP on the segment. Example: seeing atNetAddress 10.0.0.5 mapped to a MAC that doesn't match the known server NIC is the kind of anomaly this table surfaces during a suspected ARP-spoofing incident.
Examples
Walk all instances (SNMPv2c):
snmpwalk -v2c -c public <target> 1.3.6.1.2.1.3.1.1.3 snmpwalk -v2c -c public <target> CHECKPOINT-MIB-2::atNetAddress
Get a specific instance (index 1):
snmpget -v2c -c public <target> 1.3.6.1.2.1.3.1.1.3.1 snmpget -v2c -c public <target> CHECKPOINT-MIB-2::atNetAddress.1
Set instance 1 (SNMPv2c):
snmpset -v2c -c private <target> 1.3.6.1.2.1.3.1.1.3.1 a <value>
