Problema Dns

[ruddzzz]

Salve, volevo creare nella mia rete domestica 192.168.1.0/26, un dns server con Linux Fedora Core 4. I miei file di configurazione sono:

#####named.conf:##########
options {
directory "/var/named";
/*
* If there is a firewall between you and nameservers you want
* to talk to, you might need to uncomment the query-source
* directive below. Previous versions of BIND always asked
* questions using port 53, but BIND 8.1 uses an unprivileged
* port by default.
*/
// query-source address * port 53;
};

controls {
inet 127.0.0.1 allow { localhost; } keys { rndckey; };
};

zone "." IN {
type hint;
file "named.ca";
};

zone "localhost" IN {
type master;
file "localhost.zone";
allow-update { none; };
};

zone "0.0.127.in-addr.arpa." IN {
type master;
file "named.local";
allow-update { none; };
};

zone "pippo.net." IN {
type master;
notify no;
file "pippo.net.db";
allow-update { none; };
};

zone "1.168.192.in-addr.arpa." IN {
type master;
notify no;
file "192.168.1.db";
allow-update { none; };
};

include "/etc/rndc.key";

#####192.168.1.db####################
$TTL 86400
@ SOA ns.pippo.net. root.pippo.net. (
2004012300 ; Serial
3H ; Refresh
15M ; Retry
1W ; Expire
1D ) ; Minium
IN NS ns.pippo.net.
254 IN PTR ns.pippo.net.

Il mio problema è che quando eseguo dig ns.pippo.net mi da come risp:

; <<>> DiG 9.3.1 <<>> ns.pippo.net
;; global options: printcmd
;; Got
answer:

Perchè il DNS server non risponde ? Ho sbagliato nelle configurazioni ?

Grazie.
