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.

AS6461 once had the bulk of its reverse DNS auto-generated from awk scripts. It's the only way to travel.
