[trimmed]    I might not have been clear enough, the 1.0.0.0/24 example is a public /24  routable network, not a 10.0.0.0/8 network.    What I want is to be able to use as much as this network as possible (here 2 ip  per host) and allow firewall rules between hosts. The Ipv6 part is easier to  manage as I can spawn as many subnet as I want.    And the reason is that the hosts are untrusted and must be firewalled between  them, so I need layer 2 isolation.    
If they are attached to a public routeable net, wouldn't they be able to
speak to each other there?
Even if you put a filter in they could access each other using a VPN.
