I'm having a problem configuring my rDNS...
Here's my config:

My range of address is from xxx.xxx.220.89 (gw) to xxx.xxx.220.94

----------------------------------------------------------------
In named.conf I got this:

zone "220.xxx.xxx.in-addr.arpa" {
        type master;
        file "master/db.xxx.xxx.220";
        allow-transfer {
                xxx.xxx.220.93;
        };
};


----------------------------------------------------------------
in master/db.xxx.xxx.220 I got this:

$TTL 86400

220.xxx.xxx.in-addr.arpa.       IN      SOA servicos1.mydomain.xyz. servicos2.mydomain.xyz. (
                                                30         ; serial
                                                3600       ; refresh (1 hour)
                                                3600       ; retry (1 hour)
                                                3600       ; expire (1 hour)
                                                3600       ; minimum (1 hour)
                                                )

220.xxx.xxx.in-addr.arpa.       IN      NS      servicos1.mydomain.xyz
220.xxx.xxx.in-addr.arpa.       IN      NS      servicos2.mydomain.xyz

$ORIGIN 220.xxx.xxx.in-addr.arpa.
90.220.xxx.xxx.in-addr.arpa.    IN      PTR     banda1.mydomain.xyz
91.220.xxx.xxx.in-addr.arpa.    IN      PTR     banda2.mydomain.xyz
92.220.xxx.xxx.in-addr.arpa.    IN      PTR     servicos1.mydomain.xyz
93.220.xxx.xxx.in-addr.arpa.    IN      PTR     servicos2.mydomain.xyz
94.220.xxx.xxx.in-addr.arpa.    IN      PTR     albator.mydomain.xyz

----------------------------------------------------------------


Now what get is the following:
[root@banda1 /usr/ports]# host xxx.xxx.220.92
Host 92.220.xxx.xxx.in-addr.arpa not found: 3(NXDOMAIN)
