What is dnsResOptCounterNoResponses?
This counter tracks how many DNS queries were retransmitted to a resolver because the initial request received no response from the target DNS server, indicating timeouts or packet loss. High values suggest DNS server unavailability, network congestion, or unreliable connectivity to name servers. System administrators use this to identify DNS infrastructure problems and optimize resolver configurations.
