Do I need to whitelist Data Factory IPv6?

Question

Do I need to whitelist Data Factory IPv6?

Tien Nguyen 5

I want to connect my Azure Data Factory with a customer's SQL Server (also hosted in Azure). To facilitate this, I need to share the IP addresses of my ADF with the customer so they can authorize (whitelist) connections from these IPs.

I can get the most recent list of IP addresses for Azure Data Factory in North Central US from this link: https://www.microsoft.com/en-us/download/details.aspx?id=56519. As can be seen, this list contains a number of IPv4 as well as IPv6 addresses.

{
  "name": "DataFactory.NorthCentralUS",
  "id": "DataFactory.NorthCentralUS",
  "properties": {
    "changeNumber": 6,
    "region": "northcentralus",
    "regionId": 34,
    "platform": "Azure",
    "systemService": "DataFactory",
    "addressPrefixes": [
      "20.49.114.24/29",
      "20.49.118.128/25",
      "20.125.163.208/29",
      "20.125.171.208/28",
      "20.125.203.208/28",
      "40.80.185.0/24",
      "40.80.186.0/25",
      "52.162.111.48/28",
      "2603:1030:608::440/122",
      "2603:1030:608::500/121",
      "2603:1030:608:402::330/124",
      "2603:1030:608:800::2c0/124",
      "2603:1030:608:c00::2c0/124"
    ],
    "networkFeatures": [
      "API",
      "NSG"
    ]
  }
},

The question is, how can the customer whitelist these IPv6 addresses? The Azure SQL server UI only allows to "add your client IPv4 address". User's image

Hi , hope doing well

To answer your query

While the Azure Data Factory provides both IPv4 and IPv6 addresses but Azure SQL Server only supports IPv4 as Azure SQL does not listen on IPv6 (yet)., you'll have to communicate the IPv4 addresses from the ADF's list to the customer for whitelisting.

Please accept answer if it help , Thanks!

Hi, is it enough to whitelist only the IPv4 addresses? Is the list of IPv4 and IPv6 equivalent (they are all from the same set of machines)? Is there a scenario that I must whitelist an IPv6 for it to work?

Hi Deepanshu, is whitelisting only IPv4 enough? Is the list of IPv4 and IPv6 equivalent (they come from the same set of machines)? Is there a scenario where I need to specifically whitelist an IPv6 for the connection to work?

Whitelisting only IPv4 addresses might be limiting if the network or services you're working with use IPv6 exclusively or in conjunction with IPv4. While IPv4 and IPv6 often come from the same machines, they represent different address spaces, and some systems might prioritize IPv6 connections over IPv4 if both are available. so you can consider this accordingly as per your scenario
