Install/Configure BIND2014/04/19

	Configure DNS server which resolves domain name or IP address. BIND uses 53/TCP,UDP.
[1]	Install BIND 9

root@dlp:~#

apt-get -y install bind9 bind9utils

[2]	Configure BIND. This example is set 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. )

# *note : For How to write for reverse resolving, Write network address reversely like follows
For 10.0.0.0/24
network address

⇒ 10.0.0.0

network range

⇒ 10.0.0.0 - 10.0.0.255

how to write

⇒ 0.0.10.in-addr.arpa

For 172.16.0.80/29
network address

⇒ 172.16.0.80

network range

⇒ 172.16.0.80 - 172.16.0.87

how to write

⇒ 80.0.16.172.in-addr.arpa

[3]	Limit ranges you allow to access if needed.
