What is rlDnsResCacheRRInetSource?
This read-only field reports the IP address of the name server that this cached DNS record was actually received from, or 0.0.0.0 if that's not known. An administrator checks it to trace which upstream DNS server is the origin of a particular cached answer, useful when different servers are giving inconsistent results. For example, if a hostname resolves inconsistently, comparing this OID across cache entries can reveal answers are coming from two different upstream servers.
