If you are using Zoom’s Epic integration and whitelisting Zoom’s server IP addresses, please be advised where to get the list of addresses and how to be informed about updates. Zoom will add new servers to handle increased integration service loads. In some cases the new servers will have IP addresses that are within the IP range previously published by Zoom. In other cases Zoom may need to use addresses from a new IP address range. Please refer to the latest list of IP address ranges that can be found on the Zoom network firewall or proxy server settings page. Please also subscribe on the https://status.zoom.us/ to receive updates when new IP ranges are added to the list.
