Thanks for the info.

This is all getting me very confused, as it appears that the ISP that
ns2.dnsfusion.com is running on is in some way messing with/replying to my

Check out this again

About half way down, look at the 'INFO | Name Server Version' section: "Served by POWERDNS 2.9.16 $Id: packethandler.cc,v 1.24
2004/02/08 10:43:50 ahu Exp $" "Nildram DNSv0.9"

Nildram DNS!!!! Nildram is the ISP that serves ns2!

I gather from the docs that the "non-generic" backend is obsolete but for
some reason has a confusingly similar name and is still packaged.  Use
the gmysql one.

I think this is due to the second problem, see below.  The ttl returned
by ns2 is counting down each time, which suggests it has a cached answer
from a different server, while the ttl returned by ns1 is constant (as it
ought to be).

ns2 is not responding authoritatively.  You probably have it configured
as a slave -- don't!  Configure it as a primary, exactly the same as you
have configured ns1.

Not quite sure what the deal is here.  However, there are two obvious
things I would check:
- is the local mysql database on ns2 reflecting up to date data?
- if so, are you sure the server is getting data from the db?

I am a php/perl coder, and though I am relatively new to pdns (in the
last couple of months), I'm digging it, and working on some similar
integration scripts/tools myself for my systems as well.  Feel free to
get in touch.
