Really? All of them? Are you sure about that?
I believe there is a policy proposal in the ARIN region which, I have it on g=
ood authority
is still active.
True, it doesn't technically designate more RFC-1918, but, it does create a /=
10 of space
for shared use for the purpose of LSN intermediate space or other carrier-le=
vel private
network usage.

More likely they are making the assumption that their private internal use o=
f the address
space won't conflict with DoD's (apparently) private internal use of the add=
ress space.
