dns3
Module: CPI-UNITY-MIB
OID (symbolic): CPI-UNITY-MIB::dns3
OID (numeric): 1.3.6.1.4.1.30932.1.1.2.8.3
Node type: OBJECT-TYPE

Description: PDU DNS 3 IP.
What is dns3?
This read-write IpAddress object holds the PDU's third IPv4 DNS server address, a further fallback beyond dns1 and dns2. An admin populates this in environments where DNS resilience is critical and a third independent resolver is available. For example, a highly redundant facility configures dns3 with a public resolver as a last-resort fallback if both internal DNS servers become unreachable.
Examples
