Thanks, I'm trying this now, but there must be some syntax
differences in the files. I can't seem to get it to load a mysql
backend even though I have my launch line set up.<br>

when you go for a reverse lookup on 10.10.128.45 (for

it doesn’t matter that those records are hosted elsewhere

the answer and simply recourses it out for resolution.<o:p></o:p></span></p>

I'll explain my problem in a little more detail, and then
perhaps suggestions can flow:<br>
<br>
We are using dns as a registration system. Devices contact a
server and register, a dns record is created. For the sake of
this discussion, I'll refer to this as old registration system
(bind and old registration servers) and new registration
system (powerdns and new server)<br>
<br>
Many "apps" need to look up the information in dns, we have a
keepalived fault tolerant IP address that points to a name
server (currently bind), but we'd like to switch this to
powerdns. However, we can't just switch all the dns records
over at once, there has to be a transition period. So, we'd
like to switch over to powerdns and new registration server.
All new records will exist in powerdns. Eventually, all the
old records will migrate as clients re-register.<br>
<br>
So, when someone queries the new server, it needs to look up
the data first in powerdns, and if it isn't there, recurse.<br>
<br>
I tried putting the powerdns recursor in front. It did not
work for me, as each backend server thinks it is
authoritative. So if it happens to query that one first, it
returns NXDOMAIN and never looks at the next one in the list.<o:p></o:p></p>
