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.

Subdomeni

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

Kada je hostname serviran iza CDN-a (npr. Cloudflare), origin server se ponekad može identifikovati podudaranjem TLS sertifikata sa zaštićenim hostname-om. Nalazi prikazani ovde su heuristički kandidati, a ne garancija.

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.
