Install BIND2017/06/21

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

root@dlp:~#

apt -y install bind9 bind9utils dnsutils

[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 below

# 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

# range of network          ⇒ 172.16.0.80 - 172.16.0.87
