Use my awsiprangefilter.py (https://gist.github.com/brianwhigham/d3d74c17c423254db2ba973f97fae614) gist to list AWS IP ranges. Then, use ipcalc to count how many hosts are in that list.

	# usage: supply a comma-separated list of regions as the first argument
	# and a comma-separated list of services as the second argument.

	wget -O /tmp/ip-ranges.json https://ip-ranges.amazonaws.com/ip-ranges.json
	unset hostcnt
	unset tcnt
	for r in $(awsiprangefilter.py -r $1 --services $2)
