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.

jiongjun.cc 95% confidence
behind AS13335 cert 7d4682c017df… · cert 7d4682c0… served by 45.77.18.227 (AS20473) carries SAN jiongjun.cc which currently resolves through Cloudflare (AS13335) at 172.67.128.150, 104.21.2.19, 2606:4700:3033::6815:213, 2606:4700:3033::ac43:8096

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.
