"first free" unless "--ifconfig-pool-persist file" is used, then
"same client same subnet".

But you really want to use "topology subnet", which gives each client
a single /32, not wasting a /30 per client.  The default (net30) is
from really old times where the windows port couldn't handle subnet.
