Configure BIND as a Private Network DNS Server on Ubuntu 14.04
You must have the good observation in DNS otherwise you won't understand what you doing. Here I configured standalone DNS Server without a backup host.
Here is my configure:
sudo apt-get update
sudo apt-get install bind9 bind9utils bind9-doc
sudo nano /etc/default/bind9
OPTIONS="-4 -u bind"
sudo nano /etc/bind/named.conf.options
acl "trusted" {
10.128.10.11; # ns1 - can be set to localhost
10.128.100.101; # host1
};
options {
directory "/var/cache/bind";
recursion yes; # enables resursive queries
allow-recursion { trusted; }; # allows recursive queries from "trusted" clients
listen-on { 10.128.10.11; }; # ns1 private IP address - listen on private network only
allow-transfer { none; }; # disable zone transfers by default
forwarders {
8.8.8.8;
8.8.4.4;
};
sudo nano /etc/bind/named.conf.local
zone "dns.freebienow.xyz" {
type master;
file "/etc/bind/zones/db.dns.freebienow.xyz"; # zone file path
};
zone "128.10.in-addr.arpa" {
type master;
file "/etc/bind/zones/db.10.128"; # 10.128.0.0/16 subnet
};
sudo mkdir /etc/bind/zones
cd /etc/bind/zones
sudo cp ../db.local ./db.dns.freebienow.xyz
sudo nano /etc/bind/zones/db.dns.freebienow.xyz
$TTL 604800
@ IN SOA ns1.dns.freebienow.xyz. admin.dns.freebienow.xyz. (

sudo named-checkzone dns.freebienow.xyz db.dns.freebienow.xyz
sudo named-checkzone 128.10.in-addr.arpa /etc/bind/zones/db.10.128
sudo service bind9 restart
sudo nano /etc/resolvconf/resolv.conf.d/head
search dns.freebienow.xyz # your private domain
nameserver 10.128.10.11 # ns1 private IP address
