These are the IP addresses that Ivy uses to send webhook notifications. If your server implements IP filtering, you'll need to add these to your allowlist to ensure webhook deliveries are successful.

Augustus does not need to whitelist your IP addresses. The IP allowlisting is one-directional - you might be required to whitelist Ivy's IPs on your end so that your server accepts incoming webhook requests from Ivy. Ivy doesn't restrict which IP addresses can make API calls to the Ivy platform.
