Hi all

I have some problems whit the reverse dns, i have 128 ip 
my config:

zone "220.38.66.in-addr.arpa" {
        type master;
        file "/var/named/66.38.220.rev";
        };

an my zone:

$ttl 38400
220.38.66.in-addr.arpa. IN      SOA     logiktech.net. inco.logiktech.net. (
                        1001855174
                        10800
                        3600
                        432000
                        38400 )
220.38.66.in-addr.arpa. IN      NS      logiktech.net.
