Announcing IP Address Changes (No Operational Impact)

Scheduled for Feb 1, 23:59 PST - Feb 2, 00:00 PST

The table for Zoom Phone rules has been updated to include the use of the UDP protocols for TURN (Traversal Using Relays around NAT) support (UDP 3478). Due to this, we recommend that network administrators, with Zoom-specific firewall or network rules, update their systems. This update is only for the protocol; no changes have been made to the destination addresses used for Zoom Phone. Below are the IP ranges that will be utilized for TURN support (UDP 3478).

Zoom Phone IPv4 ranges for TURN support:

144.195.0.0/16
147.124.96.0/19
170.114.0.0/16
173.231.92.0/24
206.247.0.0/16

As a reminder, these ranges were previously announced and are already in use for Zoom Phone.
