WHOIS / Registration
Registration data planned
Registrar, creation/expiry dates and domain status via RDAP. Rolling out gradually — bulk WHOIS is rate-limited, so we resolve on a prioritized cadence.
Subdomains
Every subdomain we know about — harvested from CT-log SANs, scan-observed certs and HTML body references — paired with its current A/AAAA target.

Origin / IP-Leak
USP
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 |
|---|---|---|---|---|
| 195.15.202.241 | AS29222 | AS13335 | 95% | cert f56004d1… served by 195.15.202.241 (AS29222) carries SAN stackoverflow.com which currently resolves through Cloudflare (AS13335) at 198.252.206.1 |
| 195.15.202.118 | AS29222 | AS13335 | 95% | cert aff6251a… served by 195.15.202.118 (AS29222) carries SAN stackoverflow.com which currently resolves through Cloudflare (AS13335) at 198.252.206.1 |
