To ensure a secure connection, Coupa provides a complete list of our public IP addresses. With the exceptions listed on the pages linked below, Coupa has registered all IP addresses and ranges with Amazon Web Services (AWS). Coupa's newer IP addresses and ranges are registered with American Registry for Internet Numbers (ARIN).
While it is highly recommended to whitelist our entire IP ranges, you can choose to only whitelist a subset of our IP ranges. If you must do this, review the following information on the links listed below to avoid any unintended service disruptions.
