• Blacklist status: 0 explicit listings (1 DNSBL listing among 8 total checks)
• Threat feeds: No matches
• Campaign correlation: None detected
• Persistent malicious activity: No

NEIGHBORHOOD CONTEXT (51.222.168.0/24):

The /24 subnet exhibits high abuse density (0.6719) with 217 active sibling IPs and 172 identified as threats. Risk distribution across the subnet: 100 medium-risk IPs. This IP sits within a high-abuse density environment, suggesting potential collateral risk from network neighbors.

HISTORICAL OBSERVATIONS:

22 signal observations recorded. Recent activity (June 2026) confirms consistent hosting/cloud infrastructure classification with no escalation in threat indicators. No ownership changes detected.

RECOMMENDED ACTIONS:

While no specific threat indicators were identified, the moderate risk score combined with high-abuse neighborhood density warrants defensive posture. Recommended blocking rules provided for iptables, nftables, nginx, pfSense, Cloudflare WAF, and AWS WAF.

ASSESSMENT:

This IP represents a moderate-risk hosting endpoint within an OVH customer subnet. No active malicious indicators detected. However, the subnet's high abuse density suggests defensive blocking may be prudent, particularly if the IP exhibits suspicious behavior patterns. Monitor for service activity or threat indicator emergence.

STATUS: Monitoring recommended. No immediate threat indicators.
