In this tutorial, you'll learn how to configure primary and secondary DNS servers on an Ubuntu operating system. DNS servers are essential for web browsing, as they translate domain names into IP addresses. Properly configuring these servers ensures a faster and more secure internet connection. Follow the steps below to properly configure DNS on your Ubuntu system.

Guide to modifying the primary and secondary DNS on your device

DNS, or domain name servers, are responsible for translating IP addresses into domain names. In other words, they allow users to access websites using names instead of numerical addresses.

Changing the primary and secondary DNS on your device can improve the speed and security of your internet connection, as domain name servers influence how quickly web pages load and protect against malware and phishing.

If you're using Ubuntu as your operating system, follow these steps to configure your primary and secondary DNS:

Step 1: Access your device's network settings. You can do this from the home menu or by searching in the toolbar.

Step 2: Select the internet connection you want to modify. If you're using Wi-Fi, choose the corresponding wireless network; if you're connecting via cable, select the Ethernet option.

Step 3: Click on the "Settings" button and select the "IPv4" tab.

Step 4: In the "Method" section, choose the "Automatic (DHCP) with address only" option.

Step 5: In the "DNS Servers" section, enter the primary and secondary DNS servers you wish to use. You can use Google's public DNS servers (8.8.8.8 as primary and 8.8.4.4 as secondary) or Cloudflare's (1.1.1.1 as primary and 1.0.0.1 as secondary).

Step 6: Click "Apply" to save the changes.

With these simple steps, you'll have configured the primary and secondary DNS on your Ubuntu device. Remember, if you experience any connection issues, you can always revert to your previous settings or try other domain name servers.

How to configure primary and secondary DNS in Ubuntu
If you have an Ubuntu server and want to configure primary and secondary DNS, you've come to the right place! In this article, we'll explain how to do it quickly and easily.

Step 1: Install Bind9
The first step is to install the Bind9 package, which is the DNS server we'll be using. To do this, open a terminal and type the following command: sudo apt-get install bind9. Press Enter and wait for the installation to complete.

Step 2: Configure the named.conf.local file
The next step is to configure the named.conf.local file. This file contains all the information about the DNS server. To do this, open the file with the following command: sudo nano /etc/bind/named.conf.local. Inside the file, add the following lines:

zone «yourdomain.com» {
typemaster;
file «/etc/bind/db.yourdomain.com»;
};

Step 3: Create the zone file
The next step is to create the zone file for the domain you want to use. To do this, open the file with the following command: sudo nano /etc/bind/db.yourdomain.com. Inside the file, add the following lines:

$TTL 86400;
@ IN SOA yourdomain.com. email.yourdomain.com. (
2019030901;
28800;
3600;
604800;
38400;
);
@ IN NS yourdomain.com.
@ IN A 192.168.1.1
www IN A 192.168.1.1

Step 4: Restart the Bind9 server
The final step is to restart the Bind9 server for the changes to take effect. To do so, type the following command: sudo systemctl restart bind9.

Done! You've now configured your primary and secondary DNS servers in Ubuntu. We hope this article was helpful. See you next time!
