Install/Configure BIND2011/03/14
  Configure DNS server which resolves domain name or IP address.

[1] Install BIND
[root@dlp ~]#
yum -y install bind bind-utils
[2] Configure BIND This example is done with grobal IP address [172.16.0.80/29], Private IP address [10.0.0.0/24], Domain name [srv.world]. However, Please use your own IPs and domain name when you set config on your server. ( Actually, [172.16.0.80/29] is for private IP address, though. )
[root@dlp ~]#
echo 'OPTIONS="-4"' >> /etc/sysconfig/named
# set if you don't use IPv6 ( if use, don't set it )


[root@dlp ~]#
vi /etc/named.conf


//
// named.conf

// Provided by Red Hat bind package to configure the ISC BIND named(8) DNS

// See /usr/share/doc/bind*/sample/ for example named configuration files.

# *note : For How to write for reverse resolving, Write network address reversely like below.

10.0.0.0/24
network address
⇒ 10.0.0.0

range of network
⇒ 10.0.0.0 - 10.0.0.255

how to write
⇒ 0.0.10.in-addr.arpa


172.16.0.80/29
network address
⇒ 172.16.0.80

range of network
⇒ 172.16.0.80 - 172.16.0.87

how to write
⇒ 80.0.16.172.in-addr.arpa
