The main nossl.sh page shows your IPv4 immediately and calls v6.nossl.sh in the background to reveal IPv6 when available.
Everything stays on simple HTTP so captive portals and constrained devices can still display the report.
- Copy IPv4 or IPv6 with one tap.
- Share a support-ready snapshot with the built-in report link.
- Verify dual-stack reachability without running shell tools.
Built for quick triage
Refresh the page after login attempts to confirm whether the network is still intercepting traffic.
- Counters show overall usage to prove the service is up.
- Header tables expose proxies, VPNs, or custom DNS rewrites.
Will the page show IPv6 automatically?
Yes. If your network hands out IPv6, the page fetches v6.nossl.sh and displays the address alongside IPv4 so you can prove dual-stack routing.
Is the data cached?
No. Responses disable caching so every refresh returns a fresh timestamp and the latest IP info.
