The major reason to use private address space is that there is likely
a lot more of it than you have in public address space. if you have
effectively unlimited fixed_ip space, you can give each project a lot.
For example, we give each project a /23. While a user could
potentially still run out of address space on our system, it hasn't
happened yet with our workload.
