Known Vulnerabilities
Published CVEs matched to the software versions fingerprinted on this host. Matching is by product and version against the NVD dictionary — presence of a CVE does not confirm the host is exploitable (patches or backports may apply).

Origin / IP-Leak
USP
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-leak candidates for this IP
When this IP serves a TLS cert for a domain that fronts behind a CDN, that domain surfaces here as an origin-leak candidate with a confidence score.
Hosted Domains
2 domains resolve (A-record) to this IP.

No accumulated reachability data yet
Reachability accrues from real user-triggered checks. Trigger a Ping or HTTP check from our 65+ probe nodes to contribute the first data point.
Threat Intelligence
No threat-intel matches
This IP doesn't appear in any of the feeds we mirror (Tor exits, FireHOL Level 1-3, Spamhaus DROP/EDROP, URLhaus, OpenPhish). Absence here doesn't prove the IP is clean — it just means none of our public-feed sources flag it.
Co-Hosted Domains
No DNS-confirmed domains yet
We cross-reference body-cited domains against our DNS resolver records. Confirmations appear here once both sides have data for the same name.
External References
Domains the body links to whose DNS does NOT resolve to this IP — usually CDN assets, embeds, or third-party services. Boilerplate (Google Fonts, jsDelivr, w3.org…) is already filtered.
