Bash script to monitor any new device connects to a network using arp

	#!/bin/bash
	#
	# arp-monitor, an ARP tables monitor
	# inspired by https://gist.github.com/maugern/30ace2764aafc683a802de2ed82f91af
	#
	# This script is intended to start on launch and run on an always connected device on a network (eg: server).
	# It scans the network with 'arp -a' and sends a notification webhook whenever recognizes a new mac address on the network.
	#
	# For auto-run on login you can rename the script to a .command and add it to your Login items on Mac OS or
	# modify the script to remove the loop and take a look at crontab
