+Process
+*******
+
+#.	Make this directory:
+
+	.. code-block:: bash
+
+		$ sudo mkdir -p /etc/systemd/network
+
+#.	Identify the interface to be assigned the static IP address:
+
+	.. code-block:: bash
+
+		$ ip addr
+
+	The system returns the following:
+
+	.. code-block:: console
+
+		1: lo: <LOOPBACK,UP,LOWER_UP> mtu 65536 qdisc noqueue state UNKNOWN group default qlen 1000
+		    link/loopback 00:00:00:00:00:00 brd 00:00:00:00:00:00
+		    inet 127.0.0.1/8 scope host lo
+		       valid_lft forever preferred_lft forever
+		    inet6 ::1/128 scope host
+		       valid_lft forever preferred_lft forever
+
+		2: wlp1s0: <NO-CARRIER,BROADCAST,MULTICAST,UP> mtu 1500 qdisc mq state DOWN group default qlen 1000
+		    link/ether 4a:98:8d:e5:43:15 brd ff:ff:ff:ff:ff:ff
+
+		3: eno1: <BROADCAST,MULTICAST,UP,LOWER_UP> mtu 1500 qdisc fq state UP group default qlen 1000
+		    link/ether f4:4d:30:68:96:20 brd ff:ff:ff:ff:ff:ff
+		    inet 10.0.1.2/24 brd 10.54.74.255 scope global dynamic eno1
+		       valid_lft 6766sec preferred_lft 6766sec
+		    inet6 fe80::f64d:30ff:fe68:9620/64 scope link
+		       valid_lft forever preferred_lft forever
+
+	In this example, we will use the `eno1` interface.
+
+#.	Create the :file:`70-static.network` file and add the following:
+
+	.. code-block:: bash
+
+		$ sudo vi /etc/systemd/network/70-static.network
+
+		[Match]
+		Name=[interface name]
+		[Network]
+		Address=[IP address]/24
+		DHCP=yes # to get DNS info, etc.
+
+	Replace [interface-name] and [IP-address] with your specific settings.
+
+#.	Restart the networkd service:
+
+	.. code-block:: bash
+
+		# sudo systemctl restart systemd-networkd
+
+**Congratulations!** You have successfully assigned a static IP address.
