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.

No origin-IP leaks detected (yet)

Either this domain doesn't sit behind a CDN, or we haven't seen a TLS cert from a non-CDN IP matching this hostname. Run a fullscan to refresh the cert→IP cross-reference.

CT-Log Evidence

Certificates from public Certificate Transparency logs whose subject or SAN names this domain — including historic certs we never observed live.
