The problem seems to be that you are mixing apples and oranges. You
_can_ resolve the 2317 names (such as 241.241-255.z.y.x.in-addr.arpa) at
your authoritative server, what you can't do is resolve
241.z.y.x.in-addr.arpa directly. So what? I realize that it's
inconvenient (and I agree with Mark that the upstream should allow you
to slave the zone), but other than for testing, every client that comes
to your authoritative server will do so on a referral from your
upstream, so it will work for name resolution from a resolver. That's
what you care about most, right?
Rejoice in your working configuration, and move on ... life is too short
to lose sleep over things like this.
hope this helps,
