DNS Reverse Delegation

[Jim Flowers]

I've run into a problem with delegating reverse DNS using BIND 8.2.4 that I
can't figure out and I'm hoping for some guidance.

I have a couple of blocks delegated to me as w.x.y.0/23 which I handle with a
couple of zones 1) y.x.w.in-addr.arpa and 2) y+1.x.w.in-addr.arpa.

Now I want to delegate the second zone to an outsourced dns server and I can't
see how to do it.

If I create a zone file for y+1.x.w.in-addr.arpa with the following NS records:

y+1.x.w.in-addr.arpa IN NS ns1.remotedomain.tld.
y+1.x.w.in-addr.arpa IN NS ns2.remotedomain.tld.

It doesn't work and these records are not in named_dump.db.  I figure this is
because you aren't allowed to delegate a zone twice and the
y+1.x.w.in-addr.arpa zone has already been delegated by my upstream ISP.

Is there a correct way to do this or will I have to have this done by my
upstream ISP?
