This read-create TruthValue enables or disables a DNS lookup to re-resolve the MGC's domain name after Max2 retries are exhausted, using the last IP address associated with the MGC rather than any address as with Max1. Admins use this as a later-stage recovery mechanism for gateway-initiated messages that remain unacknowledged even after prior retry stages. For example, an admin diagnosing a gateway stuck trying an outdated MGC address after repeated failures would confirm this object is enabled so DNS re-resolution kicks in at the Max2 stage.
