What is dnsResCounterMartians?
This counter records DNS responses that arrive from servers the resolver did not actually query, which are considered suspicious or invalid sources. The metric identifies potentially spoofed or misdirected DNS replies that could indicate network problems or security issues. Network operators monitor this to detect DNS anomalies, misconfigured servers, or potential DNS cache poisoning attacks.
