Well you should be a *master* for 32.189.126.66.in-addr.arpa
and a *slave* for 189.126.66.in-addr.arpa. The later will
allow you to resolve local addresses when the external link
is down.
zone "189.126.66.in-addr.arpa" {
type slave;
file "189.126.66.arpa";
masters { 206.13.28.11; 206.13.29.11; };
};
zone "32.189.126.66.in-addr.arpa" {
type master;
file "32.189.126.66.arpa";
};

The zone is 32.189.126.66.in-addr.arpa not
224.189.126.66.in-addr.arpa.
33.32.189.126.66.in-addr.arpa. IN PTR pzs-gw.pzs.com.
34.32.189.126.66.in-addr.arpa. IN PTR fire2.pzs.com.

...
62.32.189.126.66.in-addr.arpa. IN PTR 66-126-189-62.pzs.com
