What is apDNSSecondaryServer?
This holds the IP address of the backup DNS server the AP falls back to if the primary DNS server is unavailable. An admin configures this to keep hostname resolution working even if the primary DNS server goes down. For example, an admin might set apDNSSecondaryServer to a public DNS resolver as a fallback if the primary internal DNS server ever becomes unreachable.
