10.10.10.1 through 10.10.10.200:
•The include rule is 10.10.10.[40-80]
•The exclude rule is 10.10.10.[60-70]
All of the devices with the IP addresses 10.10.10.[40-80] are discovered, but those
with IP addresses 10.10.10.[60-70] are discarded. Therefore, th e devices
discovered and retained have IP addresses 10.10.10.[40-59] and 10.10.10.[71-80].
