Install BIND2015/01/13

	Configure DNS server which resolves domain name or IP address.
[1]	Install BIND.

[root@dlp ~]#

yum -y install bind caching-nameserver

[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. )

# allow-query

⇒ query range you allow

# allow-transfer

⇒ the range you allow to transfer zone info

# recursion

⇒ allow or not to search recursively

# view "internal" { ** };

⇒ write for internal definition

# view "external" { ** };

⇒ write for external definition

# 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
