Auto-reverse means Auto RDNS zone creation. Where you're usually trying to translate hostnames to ip addresses, a reverse lookup translates an ip address to a hostname.

So, if I have an internal record, record.example.com @ 192.168.1.2, I can query the server to ask "Hey, who is at 192.168.1.2?" and the server would reply with "record.example.com". This works by creating not only the example.com zone, but also a "1.168.192.in-addr.arpa" zone with the proper mappings. Technitium server will ask you to create the zone if it doesn't already exist when you create an A record for a zone.

Sorry, for my benefit as well, I understand what you've said from a technical standpoint.

Do you mind elaborating on what this means real world in terms of what that allows you to do?
