fery.nf.ok.  IN NS		ns.fery.nf.ok.

ns.fery.nf.ok.  IN A	
	192.168.1.63

###########################################
Kemudian buat juga domain fery.nf.ok
1. Tambahkan pada file  /etc/named.rfc1912.zones
zone "fery.nf.ok" IN {
        type master;
        file "fery.nf.ok.zone";
        allow-update { none; };
};

2. cd /var/named/chroot/var/named/
   cp localhost.zone fery.nf.ok.zone
   vi nf.ok.zone
$TTL    86400
@               IN SOA  ns.fery.nf.ok.       root (
                                        42          ; serial (d. adams)
                                        3H              ; refresh
                                        15M             ; retry
                                        1W              ; expiry
                                        1D )            ; minimum
                IN NS           ns.fery.nf.ok.
                IN MX  10       mail.fery.nf.ok.
www             IN A            192.168.1.62
webmail   
      IN A            192.168.1.62
mail            IN A            192.168.1.62
fery.nf.ok.          IN A            192.168.1.62
ftp             IN CNAME        fery.nf.ok.



#chgrp named nf.ok.zone
#vi /etc/resolv.conf
nameserver 127.0.0.1
nameserver 192.168.1.62
#service named restart
#nslookup www.fery.nf.ok atau dig www.fery.nf.ok any atau host www.fery.nf.ok




buat kembali nama domain persis seperti langkah 1 dan 2
kemudian rubah file /etc/named.caching-nameserver.conf
yaitu merubah localhost menjadi any seperti berikut:

options {
        listen-on port 53 { any; };
        listen-on-v6 port 53 { ::1; };
        directory       "/var/named";
        dump-file       "/var/named/data/cache_dump.db";
        statistics-file "/var/named/data/named_stats.txt";
        memstatistics-file "/var/named/data/named_mem_stats.txt";

        // Those options should be
 used carefully because they disable port
        // randomization
        // query-source    port 53;
        // query-source-v6 port 53;

        allow-query     { any; };
        allow-query-cache { any; };
};
logging {
        channel default_debug {
                file "data/named.run";
                severity dynamic;
        };
};
view localhost_resolver {
        match-clients      { any; };
        match-destinations { any; };
        recursion yes;
        include "/etc/named.rfc1912.zones";
};

Hidupkan komputer 192.168.1.16
buat kembali nama domain.
