Additional Egress IP Address Range

Important – Action may be required.

As we continue to extend and improve the Umbrella service, on the 30^th April 2021, the Umbrella public egress IP address ranges will increase from 146.112.0.0/16 to also include 155.190.0.0/18. 

The Public IP address of traffic from Umbrella SIG users will appear to come from the address ranges 146.112.0.0/16 and 155.190.0.0/18. Depending on your organization, you may be required to inform service providers, accessed through the Umbrella service, of this IP address range. For example, some service providers require prior knowledge of the IP address ranges used before allowing access to their service.
