Azure-docs: About the Outbound IP address range used by the Functions App

[kogesaka]

Thank you for always providing useful information.

The "Data center outbound IP addresses" section states that when adding a whitelist, need to download Json files from the following site, and need to search Json fragments.

• Download Azure IP Ranges and Service Tags – Public Cloud from Official Microsoft Download Center
  https://www.microsoft.com/en-us/download/details.aspx?id=56519

Which fragments will be targeted is it ?

The Json fragment contains elements such as AppService and AppServiceManagement, but this address range does not include the Function App's outbound IP address.

The address of AzureCloud.<Region name> element seems to be included in the second.

Hi @kogesaka Thank you for your feedback! We will review and update as appropriate.

@kogesaka Function app is built on App Service. The default domain that is provided when creating App Service or Function App is .azurewebsites.net. So JSON fragment of App Service will cover function app as well and it will whitelist the IP of data center in which Function App is deployed.

@DixitArora-MSFT, Thank you for comment. I was able to understand the description, but please ask additional questions.
For example, if create Functions App in Japan East region, the JSON fragment has the following recognition as far as you check it :

• inbound IP addresses : AppService.japaneast
• outbound IP addresses : AzureCloud.japaneast

outbound/inbound IP addresses of the created Functions App is as follows :

@kogesaka This will cover Function app as well. If you have any other question specific to product , it would be best if you can create the product issue to the official Azure Functions Repo for better clarity. For now will proceed to close this thread as there are no doc changes required.
