CIDR is killing my nerves

Dear list users,

There is something I don't understand. If I put into named.conf

zone "168.232.212.in-addr.arpa" IN {
....
};

all is fine but one thing:
It does do reverse lookup for /24 net instead /28 net I in fact own. So far
I understand that it doesn't work. To solve the probelm, I tried this:

zone "176-28.168.232.212.in-addr.arpa" IN {
....
};

zone "176.28.168.232.212.in-addr.arpa" IN {
....
};

zone "176/28.168.232.212.in-addr.arpa" IN {
....
};

But this doesn't work. What is the syntax for my 28Bit subnet beginning on
.176?

The ISP does not have installed a delegation. But I think this should work
without my ISP delegating the CIDR block because I must be able to
reverse-resolve other hosts in 212.232.168.0/24 network on my dns servers.
With my today's config, it doesn't do it.

Thank you
Philipp
