DNS Records
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 |
|---|---|---|---|---|
| 165.227.255.196 | AS14061 | AS13335 | 95% | cert e43b5ad6… served by 165.227.255.196 (AS14061) carries SAN tailwindcss.com which currently resolves through Cloudflare (AS13335) at 172.67.68.11, 104.26.3.143, 104.26.2.143, 2606:4700:20::681a:28f |
