Dummy network scanner
A client wants you to do a security audit on his networks. The system admin provided you the IP adress range of their networks for you to scan, he has also provided you a list of IP addresses that you should not scan.
Write a script that takes an IP address range to scan and list of IP addresses to exclude from the scan as input(command line arguments)
The output of the script should be a final list of IP adresses(includes all the IP address from the range provided, excludes the IPs that client wanted to be excluded).
