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
43.240.12.160 AS133731 AS16509 95% cert 9d88ac26… served by 43.240.12.160 (AS133731) carries SAN api.deepseek.com which currently resolves through Amazon (AS16509) at 3.173.21.63
