How to setup a DNS server with bind in Ubuntu Linux

This is  a simple article to setup a DNS Server in Ubuntu. Please follow the steps to make this.  Setting up DNS Server is used to serve the new domain names using your IP. This is kind of providing webhosting.

Step1: We need to install bind 9 for this

sudo apt-get install bind9

Step 2: Configure the main Bind files. Usually, if you install Bind from the source code, you will have to edit the file named.conf. However, Ubuntu provides you with a pre-configured Bind, so we will edit another file:

sudo vi /etc/bind/named.conf.local

This is where we will insert our zones. By the way, a zone is a domain name that is referenced in the DNS server
Insert this in the named.conf.local file:

# This is the zone definition. replace with your domain name
zone “” {
type master;
file “/etc/bind/zones/”;

# This is the zone definition for reverse DNS. replace 1.168.192 with your network address in reverse notation – e.g my network address is 192.168.1
zone “” {
type master;
file “/etc/bind/zones/”;

Ok, now, let’s edit the options file:

sudo vi /etc/bind/named.conf.options

We need to modify the forwarder. This is the DNS server to which your own DNS will forward the requests

forwarders {
# Replace the address below with the address of your provider’s DNS server;

Now, let’s add the zone definition files (replace with your domain name:

sudo mkdir /etc/bind/zones
sudo vi /etc/bind/zones/

The zone definition file is where we will put all the addresses / machine names that our DNS server will know. You can take the following example for your keen understanding

// replace with your domain name. do not forget the . after the domain name!
// Also, replace ns1 with the name of your DNS server      IN      SOA (
// Do not modify the following lines!

// Replace the following line as necessary:
// ns1 = DNS Server name
// mta = mail server name
// = domain name      IN      NS          IN      MX     10

// Replace the IP address with the right IP addresses.
www              IN      A
mta              IN      A
ns1              IN      A

Now, let’s create the reverse DNS zone file:

sudo vi /etc/bind/zones/

Copy and paste the following text, modify as needed:

//replace with yoour domain name, ns1 with your DNS server name.
// The number before IN PTR is the machine address of the DNS server. in my case, it’s 1, as my IP address is
@ IN SOA (

IN    NS
1                    IN    PTR

Ok, now you just need to restart bind:

sudo /etc/init.d/bind9 restart

Now lets test our DNS Server
Step 4:

Modify the file resolv.conf with the following settings:

sudo vi /etc/resolv.conf

enter the following:

// replace with your domain name, and with the address of your new DNS server.


Now, test your DNS:


Look at the result…. Enjoy!
