It should look something like this:
# The loopback network interface
auto lo
iface lo inet loopback
# The primary network interface
auto eth0
iface eth0 inet static
address 192.168.X.X
netmask 255.255.255.0
gateway 192.168.X.X
dns-nameservers X.X.X.X
If you have more than one DNS server, just add a space between each:
dns-nameservers X.X.X.X Y.Y.Y.Y Z.Z.Z.Z
CONFIG DNS USE TERMINAL
sudo nano /etc/systemd/resolved.conf
Ctrl + O Save / Ctrl +X exit
sudo systemctl restart systemd-resolved / reboot
