I am aware of some companies that have used parts of a DoD /8 internally to address devices in the field that are too old to ever support IPV6.  Those devices also never interact with the public internet, and never will, so for them, I guess the only risk would be that some other internal system that wants to talk to those devices would not also be able to talk to any endpoint on the public internet that wound up using space allocated from that block, some time in the future.  Is that about right or am I missing some key failure point?

My question becomes, what level of risk are these companies taking on by using the DoD ranges on their internal networks? And have they quantified the costs of this outage against moving to IPv6?
