Input a list of either IP addresses or host names. If the input text file contains IP addresses, the script masks them appropriately with either a 16 or a 24 subnet mask. If the input text file contains hosts names, it first resolves IP addresses from the host names and then masks them. After masking is completed the script can either write the masked addresses to the screen or write them to a .txt file.
