but that doesnt work with powerdns on client side, at least for me.
taking your example with /31 instead of /32, the client zone would be named
"118-184.108.40.206.in-addr.arpa" and contains
118 PTR diablo.404.cx.
119 PTR xyz.404.cx.
unfortunately, this does not work with powerdns. setting up such a zone and doing a
dig 220.127.116.11 [client powerdns IP] gives a "Host 18.104.22.168.in-addr.arpa not found: 5(REFUSED)"
when renaming the zone to "82.119.85.in-addr.arpa" it works - obviously.
but this can't be correct. since the client server will give wrong answers for 22.214.171.124-117 and 126.96.36.199-255
sorry, i really can't see, what i am missing.
