If it's all the same name server, what does it matter??????????

You have one zone "c.b.a.in-addr.arpa", in which you put the names for
the IP addresses a.b.c.*, no matter what domain they're in.  You could
have 254 different domains, for all DNS cares!  You have another zone
"d.b.a.in-addr.arpa" for a.b.d.*, and another zone "e.b.a.in-addr.arpa"
for a.b.e.*.  Each of these three zones is separate and distinct, and
contains its own information.  There is no overlap.  There is no
ambiguity.  Why should there be?

zone "c.b.a.in-addr.arpa" {
	type master;
	file "zone.a.b.c";
};
...
zone.a.b.c:
$TTL	1d
@	IN SOA	...
	IN NS	...

1	IN PTR	www.santa-claus.com.
2	IN PTR	wais.memorah.net.
3	IN PTR	gopher.kwanzaa.org.
