Copy-and-share diagnostics
Use the copy buttons or the share link to send a full report—including both public IPs—to your support channels.
- Share link preserves IPv6 once detected.
- Headers and timestamps travel with the snapshot.
- Geo hint shows which ISP or NAT is in play.
Know exactly what the network sees
The page shows scheme, ports, and headers so you can confirm whether a proxy or VPN is rewriting your traffic.
- Great for ticket attachments and incident timelines.
- Plain HTTP keeps it accessible on locked-down Wi-Fi.
Can I hand this to support?
Yes. Send the share link or copy the IPs directly. Everything needed for triage lives in the snapshot.
Does the page expose private device details?
It only echoes what the request already sends—IP, headers, and timing—and is intended for diagnostics.
