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
Subdomain enumeration pending
Every subdomain ever issued a TLS cert under this apex — extracted from Certificate Transparency logs, our own scan observations and body references.
Tech Stack
Tech detection pending
Wappalyzer-rules detect CMS, frameworks, analytics, JS libs and server-side languages on this domain.
TLS Certificates
Certificate observations pending
TLS certs naming this domain in subject or SANs will appear here as our scan-layer catches them.
IPs Citing This Domain
Hosts whose HTML body references this domain. Strong signal for origin/mirror/embed discovery.
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.
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.
Threat Intelligence
Domain threat-intel pending
Matches in URLhaus, OpenPhish, PhishTank, malware feeds, and Spamhaus DBL.
History
Passive DNS — every value this name ever resolved to and when we first / last observed it. Updates every cycle of our forward-DNS crawler.
