	Variables in AutoIT are variants; they are both strings and
	numbers depending upon usage.

	... code ...
	$last_octet = $last_octet + 1

	should numerically add 1 to the extracted last octet value your
	code extracted from the IP address.

	As a simple exercise:

	Global $val
	$val = "123.4"
	$val = $val + 1
	MsgBox (0, "debug output", "val now contains: " & $val)

	should result in a message box titled "debug" containing the
	text "val now contains 124.4".

	Numerical tests against your variable will work as expected.
