If I create a floating address range like this:

  nova-manage floating create --ip_range=10.243.30.0/24

Is there any way to "block out" specific addresses in that range?  For
example, the .1 address is the network gateway, and everything will
fall apart if that address is accidentally allocated to an instance.

Similarly, our host needs an address in that range in order to route
traffic to the gateway.

Is there any way to exempt specific addresses?  I realize that instead
of allocating a /24 I could allocate a series of, say, /28 networks,
but that seems a little clumsy.

Thanks,
