Ahem. Just trying to clarify:
Have they given you addresses in this range (192.168/16)? These are
private addresses (RFC1918) and no-one *can* delegat these to you as =
they are
not meant to be visible in th epublic Internet.
If they gave you real public IP addresses, see below..
> 192.168.0.2 ns2.domain.com
> 192.168.0.3 host3.domain.com
> 192.168.0.4 host4.domain.com
> ...............
>=20
> That means the whole class C in-addr.arpa. zone only can be manage by =
ISP.
> It won't delegate classless in-addr.arpa. zone to another.

a) Hammer them with frequent changes and hope they learn to delegate for =
their
own convenience? Complain loudly if changes take too long to make and
filterto their secondaries. Complain loudly on any mistake they make in =
editing
their file.
or=20
b) find a better ISP
