What is dnsStatsNXDomain?
This OID counts how many queries resulted in NXDOMAIN responses, indicating the queried domain name does not exist in DNS. You monitor this to detect typos in client queries, misconfigured services, or potential security scanning activity. A sudden spike in NXDOMAIN responses can indicate users or malware attempting to resolve non-existent domains.
