What are Azure Bot Framework and LUIS IP Addresses [for firewall rules]?

Question

I would like to open firewall rules for Microsoft LUIS and BotFramework. They both use TCP port 443, however I need the IP address ranges to unblock the business's firewall .

EDIT: Our Bot is written in NodeJS and hosted on-premises

Answer 1

The IP addresses can change over time, so I recommend using the Get-AzNetworkServiceTag PowerShell command. Details found here: https://docs.microsoft.com/en-us/powershell/module/az.network/get-aznetworkservicetag?view=azps-6.2.0

Bot Service IPs:

$botService = $serviceTags.Values | Where Name -eq "AzureBotService"
$botService.Properties.AddressPrefixes

LUIS IPs are contained within Cognitive Services Management IPs:

$cognitive = $serviceTags.Values | Where Name -eq "CognitiveServicesManagement"
$cognitive.Properties.AddressPrefixes

FYI, the link to download the JSON list of IPs has also changed: https://www.microsoft.com/en-us/download/details.aspx?id=56519

A solutions architect at Microsoft has shared a link with me.

There are two options:

1. You can allow the IP ranges for your region.
2. You can setup a proxy to and add IP ranges to your firewall for your proxy.
