Determine the outbound IP addresses of your Azure App Service

Because some networks are locked down and only allow whitelisted IP addresses, I hear these questions a lot.

  • What IP addresses do I need to whitelist?

Question 1

For an individual Azure Web App, you can simply go to the Properties of the application:

You can click the copy button to add them to your clipboard.

Question 2

If you need to whitelist a region, I first lookup to see what region it is currently deployed in. You can find this information from the Overview page of the application.
