You reverse zone should be something like, if your network is setup as a
class B...:

zone "27.172.in-addr.arpa" {
        type master;
        file "/var/lib/bind/db.27.172.in-addr.arpa";
        allow-update { key dhcpupdate; };
};

A class C would look like:

zone "6.27.172.in-addr.arpa" {
        type master;
        file "/var/lib/bind/db.6.27.172.in-addr.arpa";
        allow-update { key dhcpupdate; };
};
