Enhanced Connection Analysis
IP Stack Reachability (IPv4 / IPv6)
Live probes check if your path supports IPv4, IPv6, or both (dual-stack). Each probe hits a tiny Cloudflare trace endpoint. Timeout ≈3.5s.
Note: Current method probes from the edge. If both rows show the same IPv6 value your client IPv4 reachability may still exist; a client-side hostname variant test is planned.
Protocol | Status | Observed IP | Latency |
---|---|---|---|
IPv4 | Probing... | - | - |
IPv6 | Probing... | - | - |
Detecting stack…
How this works
- Worker endpoints
/probe/ipv4
&/probe/ipv6
force protocol‑specific edge requests. - Returned IP = reachable. Timeout/error = likely unavailable / blocked.
- Both reachable = Dual-stack (optimal performance & failover).
- Client direct literal probes removed (CSP compatibility + reduced noise).

Data center, cloud provider, or hosting service
Classification Details
- ASN: 16509
- Organization: Anthropic, PBC
- Reason: ASN 16509 directly classified
Connection Quality
B
Protocol A • TLS A • Latency A • IPv6 C
Why this grade?
- Using HTTP/2
- TLS 1.3 security
- Low latency (12 ms)
How to improve:
- Network lacks IPv6 support
- Datacenter IP may indicate VPN/proxy

Reverse DNS:

ℹ️ About This Analysis
Connection type uses ASN + organization heuristics. Hostname lookup uses reverse DNS (PTR records). Both can be imperfect.
Data based on public BGP routing, known provider patterns, and DNS infrastructure.
