Did you forget to attach your patch(es) or sent them off-list? I
don’t see any attachments on this thread.
i'm not peter but look to the next day (Jan 5th) for the thread with
"[RFC PATCH] Add support for blocking A or AAAA queries per domain"
Correct; as mentioned I had hoped to publish it the following day.
That being said, after looking a little further into the problem, I've
realized that an NXDOMAIN response is not really the proper behavior in
this situation. It would be better to send a NODATA response, otherwise
downstream servers may decide to cache the whole domain as nonexistent
instead of only the AAAA record. It's probably as simple as changing
the "rc = F_NXDOMAIN" line to "rc = F_NOERR" in my patch, but I haven't
had a chance to try it out properly yet.
