rlDnsResNCacheErrInetCode
Module: CISCOSB-DNSCL-MIB
OID (symbolic): CISCOSB-DNSCL-MIB::rlDnsResNCacheErrInetCode
OID (numeric): 1.3.6.1.4.1.9.6.1.101.93.11.1.8
Node type: OBJECT-TYPE
Type: INTEGER
Access: read-only
Description: The authoritative error that has been cached:
nonexistantName(1) indicates an authoritative name error (RCODE = 3).
noData(2) indicates an authoritative response with no error (RCODE = 0) and no relevant data.
other(3) indicates some other cached authoritative error. At present, no such errors are known to exist.
unresolved(4) is used for 'fixed' entries that are currently unresolved.
What is rlDnsResNCacheErrInetCode?
This read-only integer classifies the type of cached negative DNS result: nonexistantName for an authoritative name-not-found, noData for a valid name with no matching record type, other for any other authoritative error, or unresolved for a 'fixed' entry still pending resolution. An administrator reads this to quickly distinguish a genuine DNS name error from a query for a record type that simply doesn't exist for that name, or from an entry that just hasn't resolved yet. For example, seeing nonexistantName tells the admin the hostname itself doesn't exist in DNS, whereas noData means the name exists but lacks the requested record type.
