While working on a private network, I captured some packets 
trying to reach off-net destinations.  After the initial panic
that something might be leaking, we figured out that these 
packets were being generated by applications which were trying
to communicate with their mother ships for software updates.

These automatic update requests would qualify as junk for 
some, not for others I suppose.
