## ANALYST NOTES

This IP address represents a residential or enterprise cable connection from Cablevision Systems with no active services. The low-risk classification is supported by:

• Zero open ports/services
• Zero active threat indicators
• Clean neighborhood profile
• No relationships to known malicious entities

However, the single high-severity listing detected in observation history warrants periodic monitoring. The absence of relationships and neighborhood threats reduces the likelihood of coordinated malicious activity from this source.
