1. Install package :

yum install bind* caching*

2. Edit Configuration File :

vim /etc/named.conf

//
// named.conf
//
// Provided by Red Hat bind package to configure the ISC BIND named(8) DNS
// server as a caching only nameserver (as a localhost DNS resolver only).
//
// See /usr/share/doc/bind*/sample/ for example named configuration files.
//

options {
    listen-on port 53 { 127.0.0.1; 192.168.0.0/24; 0.0.0.0/0; };
    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";
    allow-query     { localhost; 192.168.0.0/24; 0.0.0.0/0; };
    recursion yes;

    dnssec-enable yes;
    dnssec-validation yes;
    dnssec-lookaside auto;

    /* Path to ISC DLV key */
    bindkeys-file "/etc/named.iscdlv.key";

    managed-keys-directory "/var/named/dynamic";
};

logging {
        channel default_debug {
                file "data/named.run";
                severity dynamic;
        };
};

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


zone"example.net" IN {
type master;
file "forward.example.net";
allow-update { none; };
};

};

include "/etc/named.rfc1912.zones";
include "/etc/named.root.key";

3. Go to /var/named   and create zone for each required domain name.

forward.example.net & reverse.example.net

# vim  /var/named/forward.example.net

$TTL 86400
@   IN  SOA     ns1.example.net. root.example.net. (
        2011071001  ;Serial
        3600        ;Refresh
        1800        ;Retry
        604800      ;Expire
        86400       ;Minimum TTL
)
@       IN  NS          ns1.example.net.
@       IN  A           192.168.0.54
ns1       IN  A   192.168.0.54
redmine    IN    A    192.168.0.150
nagios    IN    A    192.168.100.120
share    IN    A    192.168.100.12
spark    IN    A    192.168.100.12

:wq



# vim  /var/named/reverse.example.net


$TTL 86400
@   IN  SOA     ns1.example.net. root.example.net. (
        2011071001  ;Serial

120     IN      PTR     nagios.example.net.
12     IN      PTR     share.example.net.
150     IN      PTR     redmine.example.net.

:wq

Example :

iplastdigit  IN   PTR  subdomain-domainname


4. Restart named service

service named restart
chkconfig named on


Test :
