Aug 28, 16:59:07 GMT+0
Planned - The published IP range for Zoom Meeting and Zoom Phone services has been updated from 192.204.12.0/22 to 192.204.12.0/23. We recommend that network administrators, with Zoom-specific firewall or network rules, update their systems as soon as possible in preparation. Mask change for Zoom Phone and Zoom Meetings service: 192.204.12.0/22 changed to 192.204.12.0/23 In addition, Zoom has updated the published IP range files to remove redundant entries that were fully contained within larger, overlapping subnet blocks for the Zoom Phone and ZoomCDN. This does not introduce any new IP ranges or remove any active ranges from service. The following adjustments have been made: ZoomPhone.txt: Two redundant entries, 173.231.92.0/24 and 173.231.94.0/24, were removed, as both are fully contained within the existing 173.231.80.0/20 range already listed in the same file. ZoomCDN-IPv6.txt: Two adjacent entries, 2407:30c0:180::/48 and 2407:30c0:181::/48, were consolidated into a single 2407:30c0:180::/47. While the ranges have been consolidated for the ZoomPhone.txt file, additional files have been generated for the individual Zoom Phone rules, specifically: ZoomPhone-TCP443.txt ZoomPhone-TCP5091.txt ZoomPhone-TCP390.txt ZoomPhone-UDP3478.txt ZoomPhone-UDP20000-64000.txt These updates have no operational impact. Network administrators do not need to take any action unless they maintain custom scripts or automation that reference the previous redundant entries We have also updated the Zoom CRC JSON file to reflect the current domains utilized for joining Zoom Meetings.

Planned - We are completing the final phase of the deprecation of the "Use Content Delivery Network" (CDN) feature in Zoom Meetings Web. The UI-side disablement was rolled out last year, and we are now performing a full backend cleanup — removing the remaining codebase and associated database tables. What Is Changing? The backend infrastructure supporting the "Use Content Delivery Network" toggle is being permanently removed. This includes: - Removal of all code related to the CDN feature - Cleanup of associated database tables The feature's UI control has already been disabled and was communicated in a prior release. This update completes the full deprecation cycle. Why Are We Making This Change? This cleanup effort is designed to reduce technical debt, streamline our codebase, and minimise the risk of future regressions. It is part of our ongoing commitment to maintaining a healthy and efficient platform. Impact on Administrators - No disruption is expected. This is a backend-only cleanup with no customer-facing impact. - No breaking changes or compatibility issues are anticipated. - No action is required from administrators or end users. This communication is being sent proactively out of an abundance of caution, in the unlikely event of any minor hiccups during the maintenance window. Questions or Concerns? If you have any questions, please reach out to the Zoom support. Thank you for your continued partnership. We appreciate your patience as we work to keep the platform robust and reliable..
