following is my experiment with wrong cidr 10.0.4.2/24:
$ quantum net-create net3
Created a new network:

$ quantum subnet-create net3 10.0.4.2/24 --name subnet3
Created a new subnet:
+------------------+--------------------------------------------+
| Field | Value |

$ quantum port-create net3 --fixed-ip ip_address=10.0.4.6
Invalid input for operation: IP address 10.0.4.6 is not a valid IP for the defined networks subnets.
