Install/Configure BIND
2010/07/19
  Build DNS server which resolves domain name or IP address. It's neccessary to configure router so that TCP and UDP packets to 53 can pass through.

[1] Install BIND
root@ubuntu:~#
aptitude -y install bind9
[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@ubuntu:~#
vi /etc/bind/named.conf


include "/etc/bind/named.conf.options";
include "/etc/bind/named.conf.local";
# make it comment

include "/etc/bind/named.conf.default-zones";
# add

include "/etc/bind/named.conf.internal-zones";
include "/etc/bind/named.conf.external-zones";


root@ubuntu:~#

view "internal" {
match-clients {

localhost;

10.0.0.0/24;

# create new


# define for external section

match-clients {

any;

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

for 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


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