Raspberry Pi DNS Settings Update 🔌

Enter Raspberry Pi with SSH.

Let's connect to Raspberry Pi over SSH with this simple command and then enter the password we keep for that whatever is your device connected over WIFI or via UTP cable.

ssh [e-mail]

Modify DNS info

Go to a specific configuration file named dhcpcd and edit it via nano command.

sudo nano /etc/dhcpcd.conf

Look for the static domain_name_servers string that at the beginning holds the # sign. It means the whole string is commented in other words not used as a command. Remove commenting sign as # and edit whole domain name server as you wish. You can go with Google's Public DNS servers that stay for 8.8.4.4. and 8.8.8.8 or select Public DNS servers on Cloudflare that stays for 1.1.1.1. Choose just one provider to paste. So based on your preference you will edit the whole string as follows. In the end, the whole string should look like this for Cloudflare's option.

static domain_name_servers=1.1.1.1

Or like this for Google's option.

static domain_name_servers=8.8.4.4 8.8.8.8

Press CTRL + X and as you'll be asked to "Save modified buffer?" press Y and then ENTER. No need to restart the whole Raspberry Pi device, just restart the dhcpcd service.

sudo service dhcpcd restart

To check if the domain name server's update was accepted and passed correctly use this last command to execute resolv file.

sudo nano /etc/resolv.conf

You should be seeing something like # Generated by resolvconf info and under it nameserver updated informations. That's all.

Thank your lucky stars. Reading this whole DNS-awesomesauce brief tutorial.
