Additionally, we’ve included a helpful FAQ section to address any potential issues you may encounter along the way. So let’s get started!

Configure Name Server Ubuntu: The Basics

The Domain Name System (DNS) is responsible for translating domain names into IP addresses. By configuring a name server, you can ensure that your DNS queries are resolved accurately and efficiently. While there are many different types of name servers available, we’ll be focusing on configuring the BIND (Berkeley Internet Name Domain) name server on Ubuntu.

Step 1: Before we start, we need to ensure that our server is up to date. Open a terminal and run the following commands:

Command	Description
sudo apt-get update	Updates your package list
sudo apt-get upgrade	Upgrades installed packages to their latest version

Step 2: Once your system is up to date, we can move on to installing the BIND name server. Enter the following command into your terminal:

sudo apt-get install bind9

Step 3: With BIND installed, we need to create a configuration file. Navigate to the /etc/bind directory and open the named.conf.local file:

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

Step 4: In this file, add the following lines:

zone “example.com” {
type master;
file “/etc/bind/db.example.com”;
};

Creating Zone Files

Step 5: Now, we need to create a zone file for our domain. Navigate to the /etc/bind directory and create a new file named db.example.com:

sudo nano /etc/bind/db.example.com

Step 6: In this file, add the following lines:

$TTL 86400
@ IN SOA ns1.example.com. admin.example.com. (
2014080901
28800
3600
604800
38400 )
; Name servers
IN NS ns1.example.com.
IN NS ns2.example.com.
; IP Addresses
ns1 IN A 192.168.1.1
ns2 IN A 192.168.1.2
