## THREAT ASSESSMENT

Individual IP Indicators:

• No detected open ports or active services
• Not listed as known attacker, spam source, or Tor exit node
• Blacklist count: 0 (individual IP)
• DNSBL listings: 2 of 8 total lists
• No known malware campaigns or threat feeds associated
• TLS certificates: None detected (firewalled/no services)

Neighborhood Context (198.244.168.0/24):

• Abuse Density: 0.75 (High)
• Classification: high_abuse
• Active Siblings: 164 out of 256 total
• Threat Siblings: 192
• Inherited Risk Score: 30
• Risk Distribution: 100 medium, 0 high, 0 low

Key Finding: Despite clean individual indicators, the IP resides in a subnet with elevated abuse activity. The high threat sibling count (192) indicates potential lateral threat exposure within the /24 network.

## RECOMMENDED ACTIONS

Immediate:

1. Monitor subnet 198.244.168.0/24 for correlated threat activity

2. Implement rate limiting on connections from this /24 subnet

3. Validate ahrefs.net DNS resolution patterns against known baselines

Firewall Rules:

• Allow: Established connections only (existing ahrefs.net relationships)
• Block: New connections from 198.244.168.0/24 if abuse patterns emerge
• Monitor: DNS queries to proxy-uk001-san132.ahrefs.net

Threat Hunting:

• Investigate 192 threat siblings in the 198.244.168.0/24 subnet
• Correlate any inbound connections with known Ahrefs services
• Track subnet-level traffic anomalies

## CONCLUSION

IP 198.244.168.132 represents legitimate enterprise infrastructure (Ahrefs) with moderate individual risk. However, the high-abuse density of its /24 subnet (0.75) warrants contextual monitoring. The IP is not currently flagged as malicious, but SOC teams should monitor subnet-level activity and be prepared for potential abuse campaigns leveraging the shared hosting environment.
