Raspberry Pi DNS Server Settings

Open the /etc/dhcpcd.conf file:

$ sudo nano /etc/dhcpcd.conf

At the bottom of the file, uncomment the following line and set the IP addresses of the required DNS servers, for example:

static domain_name_servers=

Save the changes and restart the dhcpcd service:

$ sudo systemctl restart dhcpcd

Check the DNS server settings:

$ cat /etc/resolv.conf
# Generated by resolvconf

To ensure additionally that the new DNS server settings are in place, you can install dnsutils and execute the nslookup command:

$ sudo apt update
$ sudo apt install dnsutils
$ nslookup www.shellhacks.com
