Azure Application Insights firewall rules

Question

I'm having some troubles sending telemetry data of my web application because of firewall rules are configured by IP, and the thing is that the IP for the App Insights are constantly changing (As far as I know this is because the App Insights services are behind a CDN so the IP depends on where the requests come from).

The question is if somebody knows if there is an IP range, or a lists of IPs that the IT people of my client could use to configure the firewall in order to keep allowing the telemetry traffic.

Many thanks in advance!

For anyone who ends up here in the future, they do have a list of ip address used by application insights available here: https://learn.microsoft.com/en-us/azure/application-insights/app-insights-ip-addresses

There are a ton more on the documentation page but here are the main telemetry IP's it uses:

• 40.114.241.141
• 104.45.136.42
• 40.84.189.107
• 168.63.242.221
• 52.167.221.184
• 52.169.64.244

All on port 443
