First I create a network and a subnet. network_id=0c557c5f-acf6-44c4-8c1c-cc12672d4d4f
second I update subnet with allocation_pools=[]

then I call api /v2.0/network-ip-availabilities/0c557c5f-acf6-44c4-8c1c-cc12672d4d4f
api return:
{"network_ip_availability": {"used_ips": 1, "subnet_ip_availability": [{"used_ips": 1, "subnet_id": "a5b694f7-7054-4ecc-8447-8e9a7a15c5f0", "subnet_name": "ZhNet-Subnet", "ip_version": 4, "cidr": "192.168.120.0/24", "total_ips": 256}], "network_id": "0c557c5f-acf6-44c4-8c1c-cc12672d4d4f", "tenant_id": "2fb75a1bedac449d904f71fbea5cd1d2", "total_ips": 256, "project_id": "2fb75a1bedac449d904f71fbea5cd1d2", "network_name": "ZhNet"}}
this result tell me: I have 256 available IPs in subnet. but I couldn't create a port successfully in this network.

The total number of IPs should be = the number of unions of address pool IP and used IP.
Because address pools are allowed to be deleted. There are also addresses outside the address pool, such as router addresses.
