And that is why the US military is unlikely to contact anyone at Rogers.

Lots of other companies have hijacked space like this. As I recall,
Reuters global networks began using 7/8 (along with a whole bunch of
other low numbered /8's), back in the mid 90's and nobody has
complained about that.

This kind of thing is becoming more common as more companies exhaust
the RFC 1918 space, and the DOD addresses are the prime target for
this "borrowing" activity because most folks feel that the DOD isn't
likely to run into any technical networking problems with this
"borrowing".

So we should CONDONE such borrowing and recommend a couple of /8s to
use in North America. Perhaps one could be DOD for those operators
that do not carry any DOD traffic and one could be that /8 from
Softbank Japan, 126/8 if I recall it correctly. People who carry DOD
traffic could borrow the APNIC block.

This actually reduces the pressure on the IPv4 address supply without
expensive carrier grade NAT services and makes the transition to IPv6
less turbulent.
