Important – Action may be required.
As we continue to extend and improve the Umbrella service, we've made some changes to the Umbrella public ingress and egress IP ranges:
- April 30, 2021 — We added 22.214.171.124/18
- October 30, 2021 — We expanded it from 126.96.36.199/18 to 188.8.131.52/16
The Public IP address of traffic from Umbrella SIG users will appear to come from the address ranges 184.108.40.206/16 and 220.127.116.11/16. 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.
