Microsoft IP Ranges for Fabric Notebooks

DanielSDavis — Tue, 21 Apr 2026 14:26:09 GMT

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.

Hello @DanielSDavis

The service tags associated with Microsoft Fabric is detailed here:

Service tags - Microsoft Fabric | Microsoft Learn

However, it’s important to note that Fabric Notebooks, User Defined Functions, and Data Engineering (Spark‑based) workloads do not currently have dedicated service tags.

Like you observed, you'll notice that the outbound traffic originates from Azure shared infrastructure, and points to Azurecloud.region.

Best to call the external API using Azure Function or similar service secured behind an Azure NAT Gateway. This will give them static IP addresses.

This has been a long standing issue. Microsoft is slowly migrating to the cloud.microsoft domain to get rid of that issue some day.
