I do not completely understand what's going on here, but it *looks* like you're populating
the local cache with reverse entries for remote addresses and that those reverse entries
are synthesized from A/AAAA queries discovered via dnstap.

At least that would explain why:

dig @127.0.0.1 -x 23.185.0.3

works in the example when 23.185.0.3 has nothing to do with your network.

Interesting but quite a different problem from the one I'm trying to solve which is to
make it trivially easy to auto-serve reverse answers and automagically satisfy reverse,
forward, reverse comparisons for your own networks.

This is particularly relevant to ipv6 now that many home-gamers are getting into ipv6 and
have the ability to nominate a reverse server - leastwise with the better ISPs. So mostly
the project is an ipv6 booster effort :-)

Rather than clog the list further, if you care, you can read the gories at
