Jesus Christ, those military ranges seem excessive. Is the Pentagon anti-NAT?

You gotta remember that as the Internet was being formed from DoD and ARPA research, that huge classes of address space were 'claimed' or appropriated by these organizations, well before today's firewalls and NAT techniques were developed to conserve address space. Chances are those class A addresses hide MANY firewalls and tens of thousands of nodes, so they probably ARE using those techniques to conserve address space. Of course, you won't be able to tell how efficient they're being since you can't scan them!

Even on the commercial side, it's rare to see someone return address space to the NIC, unless they go out of business. Even then, their ASN and address space can propagate for years before it's reclaimed and reapportioned.

I was surprised at how little foreign government's were represented in the list vis a vis the US. I would've thought that China, Russia, the UK, and even middle eastern states would have at least much more presence online, particularly with nodes that don't appreciate scanning.
