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 |
|---|---|---|---|---|
| 51.79.160.110 | AS16276 | AS13335 | 80% | cert 2510dcf6… served by 51.79.160.110 (AS16276) carries SAN citecamp.4ofl.dev which currently resolves through Cloudflare (AS13335) at 188.114.96.0, 2a06:98c1:3121::, 2a06:98c1:3120::, 188.114.97.0 |
