## ANALYST NOTES

This IP address represents Microsoft Azure cloud infrastructure with a moderate risk classification. The absence of open ports and services suggests proper hardening. The 2 DNSBL listings warrant monitoring but do not indicate active malicious activity. No threat indicators have been detected across the 22 observation points.

Suggested SOC Action: Monitor inbound traffic from this subnet. Block at perimeter firewall if traffic is unexpected or if organizational policy requires blocking of known Azure ranges. No immediate threat escalation required.
