What is dnsServCounterAuthNoDataResps?
This OID counts DNS responses that say 'this domain exists but has no records of that type' (like asking for an email server for a domain that doesn't have one). High counts can indicate misconfiguration or legitimate service structure. DNS administrators review this to understand query patterns and fix misconfigurations.
Examples
Walk all instances (SNMPv2c):
snmpwalk -v2c -c public <target> 1.3.6.1.2.1.32.1.1.2.4 snmpwalk -v2c -c public <target> DNS-SERVER-MIB::dnsServCounterAuthNoDataResps
Get a specific instance (index 1):
snmpget -v2c -c public <target> 1.3.6.1.2.1.32.1.1.2.4.1 snmpget -v2c -c public <target> DNS-SERVER-MIB::dnsServCounterAuthNoDataResps.1
Start monitoring DNS server host software, e.g. BIND (vendor-neutral, IETF/IANA standard) with a free 30-day trial of IPNetwork Monitor. Create custom SNMP monitor using the DNS-SERVER-MIB::dnsServCounterAuthNoDataResps OID value, configure state conditions and alerts, and monitor any DNS server host software, e.g. BIND (vendor-neutral, IETF/IANA standard) from a single console.
