What is swDNSResDynamicHostTTL?
This object reports how much longer, in seconds, a dynamically cached host entry will remain valid before the resolver must look it up again. It helps an admin understand how fresh a cached DNS answer is and whether stale entries might be causing connectivity issues. For example, a value of 300 means the cached mapping for that host will expire and be re-queried in 5 minutes.
