How much of a problem is traffic from unallocated addresses? Backbone
operators probably have NetFlow data which they could mine to find out.
On the other hand, how much of a problem is obsolete bogon filters causing
everytime IANA delegates another block to an RIR?
Or by the way, how much spoofed traffic uses allocated addresses?
