It's not unheard of to see the government cyber squatting unallocated /8 blocks too.

i am surprised that no one has mentioned that it is not unusual for
folk, even isps, to use space assigned to the us military but never
routed on the public internet.  i was exceedingly amused when first
i did a traceroute from bologna.
