I saw this message that went unanswered. I have the same question: what IP addresses / CIDR block does Appwrite functions use?
I need to set an allow-list in my firewall to allow Appwrite to invoke it. This is a pretty common security pattern.
TL;DR
Developers are trying to find out what IP addresses/CIDR block Appwrite functions use to set up an allow-list in their firewall. This is a common security measure.
