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.

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.

Multi-Vantage Check

Reachability accrued passively from real user-triggered checks across our 65+ probe nodes. Run a live check to add fresh data.

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

Matches against threat-intel feeds we mirror (Tor exit list, FireHOL, Spamhaus DROP/EDROP, URLhaus, OpenPhish). Each row counts the (feed, category) pair — same IP on multiple mirrors of the same feed collapses to one row.

Honeypot Activity

Seen scanning

This IP hit our honeypot sensors 8 times in the last 90 days — unsolicited connections to services we never advertise, a strong scanner / brute-force signal.

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.
