This is very interesting.
I have never read about this before, so I'd guess you are the first,
there seems to be a bug in your tool - I played a bit, it has done >
70kb requests and has not found a reverse entry I know exists - and I
confirmed that your technique work on that DNS server.
I decided to add this functionality to the dnsdict6 tool in my thc-ipv6
