Changing the DNS server in Ubuntu can actually increase your network speed and eliminate internet problems in Linux. It's a common troubleshooting step to fix it.
Hi Guys, in today's content, as the techdataz team, we will tell you how DNS or Domain Name Server, you should know how human-friendly domain names ( for example, www.techdataz.com ) are machine readable and the internet infrastructure that translates them into IP addresses ( for example, 192.0.2.1 ) is important. Never forget that it has a component.
DNS is actually needed to forward this internet traffic to the right destination, different ports can get in the way, but it's best to do this with DNS forwarding and most internet-based services, including email and file transfer, use DNS in some way. If you have the best configured DNS controls in place, this will be the best for you.
Generally, Internet Service Providers automatically provide a default DNS for your network or can come to you manually and provide it in the most powerful way. However, for potentially faster and more reliable service, using private or third-party DNS is the most reliable setup system for you.
Actually, friends, we would like to tell you that you can change the DNS server in Ubuntu by editing a configuration file through the network settings or using a different command line.
Change DNS Through the GUI Network Settings
Generally speaking, to change network settings, it would be best for you to log in to Ubuntu as an administrator and follow the steps below.
Actually, when we look at it in general terms, you should go to Settings, which you can find in the Application drawer. Then you have to click on the Network tab at the top of the left sidebar.
Now, friends, let's come to the benefits of beans: The techdataz team tells you such idioms from time to time, don't be offended, our aim is for you to read our content in the best quality and most comfortable way and in the most natural way. Now we come, in the Network settings you will see your Wired and Wireless network connection here. You will need to click on the Gear icon next to it to open the drop-down menu with multiple tabs.
Actually Now go to the IPv4 tab and make sure that the IPv4 Method is set to Automatic ( DHCP ) because this is set automatically. Just below that you will see the DNS setting. You should turn off the Automatic button next to it, turn it off.
Now in the generalization add the New DNS server IP addresses separated by commas into the blank field and click Apply. From the moment you click on Friends, you will need to verify that the IP address is correct and secure, which is critical to your network and privacy.

Using the Command Line
If you are using Linux, we would also like to say that you will probably prefer to operate via the terminal. Yes, friends, we are now showing you how you can change the DNS in Ubuntu via the command line as the techdataz team.
Open terminal and you should run:
sudo nano /etc/resolv.conf
Now we are proud to present to you what is actually happening and you can have no doubt as this will open the file containing the current DNS server settings. It will open this file anyway.
You must replace the existing nameserver IP address with the new DNS server IP address you want to use. Again, to stay safe, you should definitely make sure that you are using a reliable DNS server.
Press Ctrl + O and Enter to save the changes. Then, press Ctrl + X to exit nano.
Restart the networking service by running:
sudo systemctl restart NetworkManager
We would like to tell you as the techdataz team that you have now successfully changed the DNS in Ubuntu using the command line.
Easily Change Your DNS on Ubuntu
We think we have explained to you the easiest and simplest process to change DNS in Ubuntu, which you can do by editing the configuration file in the terminal or through the GUI network settings.
