Setting up static IP address in Debian Linux is easy. In this simple guide, I will be configuring the IP address using the old way (ifconfig) and requires that you have system administration rights to do the following steps:
Open the network interface file with the following command:
sudo vi /etc/network/interfaces
Once opened you might see something similar like this

Your interface label might be different from the example but in this case we are interested in making interface ens33 to have a static IP. I configured interface ens33 as follows:
# This file describes the network interfaces available on your system # and how to activate them. For more information, see interfaces(5). source /etc/network/interfaces.d/* # The loopback network interface auto lo iface lo inet loopback # The primary network interface allow-hotplug ens33 iface ens33 inet static address 192.168.1.200 netmask 255.255.255.0 gateway 192.168.1.1 dns-nameservers 1.1.1.1 8.8.8.8
