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.

com.tw 95% confidence

behind AS13335 cert 53793f1edda0… · cert 53793f1e… served by 41.85.185.50 (AS28683) carries SAN advantech.com.tw which currently resolves through Cloudflare (AS13335) at 104.18.5.124, 104.18.4.124, 2606:4700::6812:47c, 2606:4700::6812:57c

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.
