The following network numbers were pulled from a program called "smurf".
The program sends a large amount of spoofed traffic at broadcast addresses, 
hoping their echo packets will be magnified and sent to the spoofed address.  
The providers/machines most commonly hit are IRC servers and providers.
To prevent from being an intermediary, one must turn off "ip directed
broadcasts" on the router's interface.
