INTELLIGENCE NOTES
This IP represents a typical residential endpoint within a high-abuse subnet. The moderate risk score combined with route instability and single DNSBL listing suggests potential for opportunistic abuse. The subnet's 85% medium-risk distribution indicates systemic issues affecting the broader /24 block. Monitoring this address alongside its 161 other active siblings may reveal coordinated abuse patterns or infrastructure sharing.
