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
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 |
|---|---|---|---|---|
| 23.12.210.146 | AS9498 | AS16625 | 95% | cert ef1642f8… served by 23.12.210.146 (AS9498) carries SAN image.email.springjapan.com which currently resolves through Akamai (AS16625) at 184.24.21.74, 2a02:26f0:fe00:193::1621, 2a02:26f0:fe00:199::1621, 2a02:26f0:1180:688::1621 |
| 23.39.82.69 | AS45758 | AS16625 | 95% | cert ef1642f8… served by 23.39.82.69 (AS45758) carries SAN image.email.springjapan.com which currently resolves through Akamai (AS16625) at 23.201.243.153, 2600:1408:c400:1883::1621, 2600:1408:c400:1889::1621, 184.24.21.74 |
