TLS Certificates
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
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.
Hosted Domains
5 domains resolve (A-record) to this IP.
| Domain |
|---|
| autoconfig.carusseldwt.com |
| autodiscover.carusseldwt.com |
| autodiscover.mail.carusseldwt.com |

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
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.
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.
