How to check if Azure public IP is 'associated' via Python SDK

Question

I am trying to get a list of Public IP addresses that are not associated to any azure resource. That is 'orphaned public ip addresses'. I want to know if Azure public IP is 'associated' via Python SDK.

Using the below SDK:

from azure.mgmt.network import NetworkManagementClient
network_client = NetworkManagementClient(credential, SUBSCRIPTION_ID)
public_ip_list = network_client.public_ip_addresses.list_all()

Iterating over 'public_ip_list' will give me all the details regarding IP, but it wont say if it is 'associated' with any azure resource or not.

You can use the below to get both associated and non-associated Public IPs with Azure service using Azure python sdk.

You can get the public IP that is not associated with Azure resource when you set ip_config to none and also you can get the count of both associated and non-associated IP.

Code:

from azure.mgmt.network import NetworkManagementClient
from azure.identity import DefaultAzureCredential

credential = DefaultAzureCredential()
Subscription_id="your-subscription-id"
network_client = NetworkManagementClient(credential,Subscription_id)

public_ip_list = network_client.public_ip_addresses.list_all()
associated_count = 0
non_associated_count=0
for public_ip in public_ip_list:
    if public_ip.ip_configuration is None:
        non_associated_count+=1
        print(f"Public IP address {public_ip.name} is not associated with any Azure resource.")
    else:
        associated_count += 1
        print(f"Public IP address {public_ip.name} is associated with Azure resource {public_ip.ip_configuration.id}.")
print("Count of Non-associated with resource:",non_associated_count)
print("Count of associated with resource:",associated_count)

Sample Output:

Public IP address xxxxxxx is associated with Azure resource /subscriptions/xxxxx/resourceGroups/xxx/providers/Microsoft.Network/networkInterfaces/xxxx/ipConfigurations/primary.
Public IP address xx is not associated with any Azure resource.
Count of Non-associated with resource: 26
Count of associated with resource: 79
