Live Client Trace

Polls /cdn-cgi/trace every 5s. Changes to IP or location are logged to the browser console and highlighted below.

Waiting for first reading...

Note: the reported IP reflects the connection this page is using, which the browser pools and reuses. If http shows h3 (HTTP/3 / QUIC), the connection migrates across network changes, so switching VPN may not change the IP here until a new connection opens (close all browser windows and reopen). Disable HTTP/3 on the Cloudflare zone to make VPN switches detectable over HTTP/2.

Opera Proxy Resolution

Opera Mini / Opera mobile proxy through Opera's network, so Cloudflare sees the proxy IP. When detected, the real client IP is read from X-Forwarded-For and geolocated; the result is returned as the X-IpCountry response header.

Request Details

Headers sent by the browser + headers injected by Cloudflare, plus the CF metadata object.
