- Ownership:
- ASN: 211298
- Organization: Driftnet Hostmaster
- Network: UK-DRIFTNET-20180301 (RIPE)
- Geolocation:
- Country: United Kingdom (GB)
- City: Manchester
- Coordinates: Inferred (51.5081, -0.1278) | Accuracy: ±500km
- Timezone: Europe/London

- No direct malicious activity detected.
- Listed on 2/8 DNSBLs (low-severity listings).
- No known attacker, spam, or Tor associations.
---
**2. Observation History**
- Key Signals:
- DNSBL Listings: Identified on 2 out of 8 DNSBLs (e.g., Spamhaus, OpenBL).
- Geolocation Inference: Multiple probes confirmed UK origin, but ICMP validation failed.
- Network Stability: BGP route stability score: 0.26 (Basic).
- Trends: No significant changes in risk or activity over time.
---
**3. Relationships & Network Context**
- DNS Associations:
- Linked to `r4-3-3.monitoring.internet-measurement.com` (likely a measurement infrastructure node).
- Network Peers:
- Same subnet (`185.247.137.0/24`) with 100 neighbors.
- Abuse Density: 0% (subnet appears clean).
- High-Risk Neighbors: 0; Medium-Risk Neighbors: 35; Low-Risk Neighbors: 65.
---
**4. Threat Assessment**
- Likelihood of Compromise: Low. No direct indicators of exploitation or malicious activity.
- Red Flags:
- DNSBL listings suggest potential spam or abuse activity, though not confirmed.
- Inferred geolocation may be inaccurate due to ICMP blocking.
- Recommendations:
- Monitor DNSBL status and investigate `internet-measurement.com` for potential measurement or spoofing activity.
- Track subnet stability, as BGP route instability could indicate network misconfiguration or adversary activity.
---
Next Steps:
- Validate DNSBL listings with upstream providers.
- Correlate with internal threat intelligence for context.
- Ensure network segmentation to isolate high-risk subnets.
