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.

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.

Hosted Domains

1 domain resolve (A-record) to this IP.

Multi-Vantage Check

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

ICMP responsive This IP replied to our global ICMP sweep — last confirmed 2026-08-04.

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.

nav.aigcbar.com DNS-confirmed
nav.aigcbar.com 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.
