## Recommended Security Actions

Based on the moderate risk profile and existing firewall rules, the following actions are recommended for defensive implementation:

Note: These recommendations should be combined with additional threat signals before implementation. The moderate risk score warrants conservative blocking posture.

---

## Analysis Notes

While the IP is associated with Microsoft Azure infrastructure (typically benign), the moderate risk score (50) and presence on 2 of 8 DNSBL lists suggest potential use in spam or abuse scenarios. The lack of open services and clean neighborhood activity indicates the IP may be used for infrastructure purposes or previously flagged for outbound abuse. SOC teams should monitor for any changes in reputation or emergence of threat indicators.
