If they're on the same physical network, they _aren't_ separate from a
security standpoint. Forget this. You might configure the machines to
not use these addresses using iptables or something, but that is
machine-internal policy. If users can plug other things into the network
or if any uses can configure a machine's network settings you are not
secure. No more than a lot of people in a room agreeing not to look at
each other are. If you want actual security, you need two rooms with a door
(i.e. two physical networks with a firewalling router).
