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
185.125.100.31	AS210644	AS16509	95%	cert bae177f2… served by 185.125.100.31 (AS210644) carries SAN yahooinc.com which currently resolves through Amazon (AS16509) at 76.223.84.192, 13.248.158.7
