The IP address change has been completed. Integration hostnames will now resolve to new IP addresses in the 52.59.243.192/26 range. The old IP address range will continue to respond to traffic for the next two weeks. After September 28th at approximately 4pm EDT, the old IP address will be decommissioned and will no longer respond to traffic. If your firewall is explicitly whitelisting Duo Security, please verify that the new IP address range is included to ensure a seamless transition.
Another notice will be sent when this final change is initiated and complete on September 28th.

Scheduled
As we expand our infrastructure, we are transitioning integrations on DUO38 to a new IP range. Starting Wednesday, September 14, 2016, your integration hostnames will resolve to new IP addresses in the 52.59.243.192/26 range. The current IP address range will continue to respond to traffic for the two following weeks.
On September 28, 2016, Duo will remove current IP addresses from our systems, leaving only the new IP range. If your firewall is explicitly whitelisting Duo Security, please verify that the new IP address range is included to ensure a seamless transition.
If you have any questions regarding this change please contact our technical support department for further assistance.
