Best practices now-a-days is to use public IPs only for publicly
accessible systems and to use an IP out of the private range for
everything internal.

Internet routers _WILL_NOT_ route packets to a system with a private
IP.  Thus, it's some extra security.  If somebody find a hole into the
network, they can't talk to your internal equipment.

The corporate office wants all the hospitals in the system to convert to a 10.x.x.x addressing method.  Since all the locations use NAT to connect to the private network and then through the corporate office to the outside world, that doesn't make sense to me.  Is there any rationale for changing addressing behind a NAT firewall?
