The following IP subnet ranges are no longer in use and will be removed from Zoom resources starting no earlier than 30 days from the posting of this notice (July 7). We recommend that network administrators, with Zoom specific firewall or network rules, update their systems as soon as possible in preparation.
Removed IP address ranges:
Additionally, Zoom has been able to work with its CDN provider to obtain dedicated static IPs within the previous existing ranges for that provider. These CDN IP addresses are used to optimize the delivery of recordings and other assets from the Zoom website. These ranges are not used for the in-meeting experience.
