This IP belongs to Microsoft Azure infrastructure. The moderate risk score is a function of the IP being a cloud endpoint rather than evidence of malicious activity. The presence of stretchoid.com reverse DNS is consistent with Microsoft's internal DNS infrastructure.

Recommended Action: Allow traffic with standard Azure cloud security policies. No threat-blocking required. Monitor for any behavioral anomalies inconsistent with cloud infrastructure patterns.
