      Q. How do I know how many IPs I have left, and what IP ranges are currently available?

      A. You can follow the examples below to find your current IP ranges and availability:

      First, find the network_id for each of the networks using the neutron net-list command with egrep as shown below:

      (The values returned here are example networks.)

      > neutron net-list | egrep "external|internal"
| 0d13276b-c364-443a-9217-4af45e9e38f1 | external     | #this is the external network_id
46f82bc8-d180-46dd-9914-8733eddae793 159.122.122.160/27 | #this is the subnet_id for the external network
| ef5fb554-5e9b-4ab6-9fb4-0711c3c91e39 | internal  |   #this is the internal network_id
75f80035-fed4-4e17-9b2f-ab76143f95eb 192.168.0.0/22     | #this is the subnet_id for the internal network

      Next, enter the network_id of the external network to find available IPs there:

      > neutron net-ip-availability-show 0d13276b-c364-443a-9217-4af45e9e38f1

      You will get back something like this:

| network_name           | external                                                    |

      Next, enter the network_id of the internal network to find availability there:

      > neutron net-ip-availability-show ef5fb554-5e9b-4ab6-9fb4-0711c3c91e39

      You will get back something like this:
