Hi Zoom Community 👋

Zoom has announced updates to IP subnet ranges and network configurations for various services. New and updated IPv4 ranges have been added for Zoom Phone and Zoom Contact Center, with specific ranges for HTTP Call Widget requests in the Flow Editor. Additionally, one IP range (16.63.29.0/24) has been removed from Zoom Meeting and Cloud Room Connector services due to migration to larger contiguous ranges. Network administrators should update firewall and network rules to accommodate these changes. Zoom has also introduced new URLs for client certificate validation, which should be added to network configurations.

However, we wanted to notify you all of this change. Please be sure to follow our network firewall page to do network ACL in your edge devices for incoming traffic.
