Below it seems that it answers just fine though.<br>

Mainly that dig or nslookup off of the pdns-authoritative server, with recursion enabled, would end up with an actual PTR answer. You mention that BIND just happens to do both at the same time..is that something that PDNS can't do, or something I'm doing wrong, or in general a false perception of what is right?</div><div><br></div><div><br></div><blockquote class="gmail_quote" style="margin:0px 0px 0px 0.8ex;border-left-width:1px;border-left-color:rgb(204,204,204);border-left-style:solid;padding-left:1ex">Here you ask with the "rd" aka recursion desired flag and it appears that your BIND Server is indeed configured to recurse for you and go ask <a href="http://ns17.bitronictech.net" target="_blank">ns17.bitronictech.net</a> about the PTR for 100.94.145.204.in-addr.arpa.
