At a minimum, I was mulling over the idea of writing a script that would poll a device via SNMP to obtain interface information, parse it, compare the results to DNS, then generate a report if it found a miss. It wouldn't be fully-automated, but it would be better than doing that portion of the work manually. Cleaning up dead entries would be another issue.
