I was in a situation where I needed to get all outbound IP addresses over multiple subscriptions for IP whitelisting purposes. With the help of PowerShell I created a little script that will do just that here is an example of the output: ` .\Get-AppServiceWebAppsOutboundIpAddresses.ps1' -SubscriptionName 'mysub1','mysub2` ```powershell Switching to subscription mysub1 Switching to subscription mysub2 Count IpAddress Sites ----- ---- ----- 2 13.85.17.60 {sub1-bi-dev-as-webapp, sub2-bi-prod-as-webapp} 2 13.85.20.144 {sub1-bi-prod-as-webapp, sub1-bi-dev-as-webapp} 2 13.85.22.206 {sub2-bi-prod-as-webapp, sub1-bi-dev-as-webapp} 2 13.85.23.148 {sub1-bi-dev-as-webapp, sub2-bi-prod-as-webapp} 2 13.85.23.243 {sub1-bi-dev-as-webapp, sub2-bi-prod-as-webapp} 1 23.96.184.12 {sub1-dev-functions-mmckydd} 1 23.96.184.209 {sub1-dev-functions-mmckydd} 1 23.96.186.252 {sub1-dev-functions-mmckydd} 1 23.96.187.50 {sub1-dev-functions-mmckydd} 5 23.96.244.71 {sub1-stg-webapp-web-n7wfdda, sub1-stg-functions-n7wfdda, sub1-stg-webapp-admin-n7wfdda, sub1-dev-ops-functions-stl4tn5...} ``` If you are interested to have a sorted, unique list of IPs used in your App Services, this script is for you.
