Hi Olivier Nicole
Tnx for ur quick response.
I'm very very new to both DNS and Freebsd.
Maybe I'm stupid because I already spent 3 days creating my zone file 
and reverse file
but I still can not sussefull.
I'm running FreeBSD 6.2, I have DynamicIP: www.thecuong.gotdns.com.
Could you help me to create the simple example  of zone file and reverse 
file for me
for thecuong.gotdns.com so that I can learn from you?
I'm really really stuck.

Below is my named.conf:
options {
    directory    "/etc/namedb";
    pid-file    "/var/run/named/pid";
    dump-file    "/var/dump/named_dump.db";
    statistics-file    "/var/stats/named.stats";

    listen-on    { 127.0.0.1; 192.168.0.1; };

      forward only;

    forwarders {
        210.245.0.131;
    };

};

zone "." {
    type hint;
    file "named.root";
};
-------------------------------------------------------------------
And below is my localhost.rev:

;    From: @(#)localhost.rev    5.1 (Berkeley) 6/30/90
; $FreeBSD: src/etc/namedb/PROTO.localhost.rev,v 1.6 2000/01/10 15:31:40

;
; This file is automatically edited by the `make-localhost' script in
; the /etc/namedb directory.
;

$TTL    3600

@    IN    SOA    localhost.localdomain. root.localhost.localdomain.  (
                20070713    ; Serial
                3600    ; Refresh
                900    ; Retry
                3600000    ; Expire
                3600 )    ; Minimum
    IN    NS    localhost.localdomain.
1    IN    PTR    localhost.localdomain.
