Open Ports

Port-scan data not yet ingested

Open-port and banner-grab data from our scan layer will appear here. World-sweep covers all IPv4 over time — this host may be in a /8 we haven't reached yet.

TLS Certificates

TLS certificate observations pending

Once our scan layer captures a TLS cert from this IP, certificate chain, JARM and JA4S fingerprints will appear here.

Tech Stack

Wappalyzer fingerprinting pending

HTTP-body analysis identifies web frameworks, CMS platforms, analytics, JS libraries and server-side languages from this host.

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.

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

No external references found yet

As HTML bodies get banner-grabbed, references to external domains land here.

History

Historical change-log pending

ASN changes, prefix re-allocations, cert rotations, port-state diffs over months — accumulates as our archives grow.
