Origin / IP-Leak
When a hostname is served behind a CDN (e.g. Cloudflare), the origin server can sometimes be identified by matching its TLS cert against the protected hostname. Findings shown here are heuristic candidates, not guarantees.
| Origin IP | Origin ASN | CDN ASN | Confidence | Reasoning |
|---|---|---|---|---|
| 178.251.4.100 | AS48854 | AS13335 | 95% | cert 0b07b8c3… served by 178.251.4.100 (AS48854) carries SAN kaufmann.dk which currently resolves through Cloudflare (AS13335) at 104.26.0.178, 104.26.1.178, 172.67.72.133, 2606:4700:20::681a:1b2 |
