+#!/usr/bin/env bash
+#
+# Usage:
+#	1) Save as: set_dhcp_requested_ip.sh
+#	2) Make executable:
+#		chmod +x set_dhcp_requested_ip.sh
+#	3) Run as root, passing the desired IP:
+#		sudo ./set_dhcp_requested_ip.sh 192.168.1.50
+#
+# What it does:
+#	- detects the primary network interface
+#	- writes a Netplan config with DHCP enabled
+#	- adds a systemd-networkd DHCPv4 RequestAddress=<IP> override
+#	- applies the config
+#
+# Important:
+#	- the router/DHCP server may ignore the requested IP
+#	- for guaranteed assignment, make a DHCP reservation on the router too
