fixed range is likely fine. I suspect you created your network with a 10.0.0.0/24 though. It might be a bit tricky to switch to a larger range now. You may have to create the rest of your fixed ips manually in the db associated with the same network and then change the cidr entry on the network in the db to 10.0.0.0/16. You also might have to manually destroy the bridges and let nova-network recreate them.
