Even though `zero-trust-client.cloudflareclient.com` and `notifications.cloudflareclient.com` may resolve to different IP addresses, the Cloudflare One Client overrides the resolved IPs with the IPs listed above. To avoid connectivity issues, ensure that the above IPs are permitted through your firewall.
Starting with Cloudflare One Client version 2026.6.0, the client uses `api.devices.cloudflare.com` instead of `zero-trust-client.cloudflareclient.com` and `notifications.cloudflareclient.com`. Even though `api.devices.cloudflare.com` (or `zero-trust-client.cloudflareclient.com` and `notifications.cloudflareclient.com` in versions earlier than 2026.6.0) may resolve to different IP addresses, the Cloudflare One Client overrides the resolved IPs with the IPs listed above. To avoid connectivity issues, ensure that the above IPs are permitted through your firewall.
