Azure-docs: When Outbound IP Addresses Change on Azure App Services

[Yashuaa]

I'm sorry, am I the only one here finding this a little ridiculous? Is there some sort of event / webhook that Microsoft can provide so that we can actually prepare for the outbound ip change? According to this logic, let's assume we have outbound ips set on a azure sql server firewall. When Microsoft decides to randomly change these outbound ips on our app service, the developer and company will have NO IDEA the app service can no longer access the azure sql server UNTIL a user complains or someone notices an error. Is the only solution Microsoft has for this issue is 'wait until it breaks then go paste in the new outbound ips in real quick , no biggie' . I mean, seriously?

On your app service, have a look at the "Properties" blade, and on the line "Additional Outbound IP Addresses" will be the superset of all possible IP addresses that your service will be seen as coming from. Whitelist those, and you'll be fine.

@LarrySmith-1437 So if the outbound IPs do change, they will never change to anything other than those additional ips listed in my app service property, is that correct?
