[dns-operations] IPv6 PTR records

Oh, Oh,

I am Peter Dambier and I am a digger.

I am using "dig -x" to find out who is hiding behind an ip-address.

I cherish the old times when "dig axfr" kept telling you everything
you ever wanted to know.

Today you have to run a resolver for somebody else and keep a
database with all queries and answers to see behind the scenes.

That is almost what I do:
Running nameservers for the Pirates Party and the Cesidian Root
and no, I do not run a database and I don't keep logs.
Even if I wanted to - my disks are not big enough.

Seen from time to time with "named -g" only the error messages
suggest 90% to 98% of all queries are nonsense in the first place.

I am running my own little nameserver at home because I do not
want to pollute the internet with my nonsense queries
and I do not trust other people's nameservers in the first place.
