Thank you Jan and Kalpesh.
At the moment, my pdns listens on 127.0.0.1 while the recursor listens on
I do understand the suggestion of using the alias IP.
However, coming from BIND, my mind is transfixed with the single daemon
which can do both authoritative and recursion (selectively). Does it mean
that with pdns, I have to run at minimum THREE separate servers - one
master, one slave, one recursor?
One other question I asked was why I am not able to resolve queries for
domains hosted by my ISP. With BIND (sorry to always refer to it) running
cache-only on my machine, things work fine.

I can't hear you -- I'm using the scrambler.
