Microsoft IP Ranges for Fabric Notebooks

I've read through all the forums on IP Whitelisting for Microsoft Azure, and most point to this resource here: https://www.microsoft.com/en-us/download/details.aspx?id=56519.  I'm working with a vendor that requires IP Whitelisting to access their API, but they are insisting we determine WHICH tags are relevant for Microsoft Fabric since the download appears to have IP ranges for all of Azure.  Initially we provided sections around Fabric and Data Factory thinking that would suffice, but it didn't work. 
We tested a call against https://api.ipify.org?format=json using:

import requests

ip_json = requests.get("https://api.ipify.org?format=json", timeout=30).json()
print(ip_json)

This returned 20.124.34.24 which fell in the range 20.124.0.0/16 under AzureCloud.eastus.  AzureCloud seemed a bit more generic than I would have expected.

Does anybody have a more refined list of which Service Tags apply to calls from Azure Data Factory, Synapse, Fabric Pipelines, User Data Functions, and Fabric Notebooks (ie spark nodes).

For our purposes, we are using python in Fabric Notebooks to perform the API calls, but we want to ensure the whole range is provided.  For whatever reason they will not just Whitelist the entire stack from the json file.
