Receive IPs from JSON file - json

Question

I am trying to get all IPs from a JSON file using Python 2.7.5
However I can not manage to do it correctly.
Do someone have an advice how I can receive all IPs from ('addressPrefixes') in a txt file?
Here is the code I already got to download the json file:
import urllib
import json
from urllib import urlopen
testfile = urllib.URLopener()
testfile.retrieve("https://download.microsoft.com/download/7/1/D/71D86715-5596-4529-9B13-
DA13A5DE5B63/ServiceTags_Public_20210426.json", "AzureIPs.json")
print("---SUCCESSFULLY RECEIVED MICROSOFT AZURE IPS---")
with open('AzureIPs.json','r') as f:
data = json.load(f)
the JSON file contains many IPs and IP Ranges and looks like this:

ips = []
values = data['values']
for block in values:
ips.append(block.properties.addressPrefixes)
However you will get 2D array using this approach, if you need 1D array and not separate block of IPs from each corresponding block in values, you can use following code to flatten the array.
import numpy as np
2DArray = np.array(ips)
1DArray = 2DArray.flatten()
