Domain Name and IP Ranges of Mirror API

Question

The Mirror API allows you to subscribe to notifications that are sent when the user takes specific actions on a Timeline Item or when the user location has been updated. When you subscribe to a notification, you provide a callback URL that processes the notification.

What are Mirror API's domain name and ip ranges when it comes to my notifyCallback url to pass me notifications from glass?

It is important because I have to allow its ips at my firewall.

Answer 1

I allowed this ip range for Google at my firewall and now I can get requests from Mirror API:

66.249.80.0 / 255.255.240.0
