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.

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).

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.

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

Domains this host references in its HTML AND whose DNS A/AAAA record resolves back to this IP — i.e. actually hosted here.

www.jdes.tyc.edu.tw DNS-confirmed

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.
