Summary:
The IP address 20.243.194.84/32 is registered to Microsoft Corporation (ASN 8075) and is part of Microsoft Azure infrastructure. It exhibits moderate risk (risk score: 50) with no direct threat indicators (e.g., no malware, phishing, or exploitation activity detected). The IP is geolocated to the United States but with ambiguous regional/city data.
Key Findings:
1. Network Context:
- Owned by Microsoft Corporation (MSFT), classified as a cloud compute node.

2. Threat Observations:
- No malicious indicators (e.g., spam, botnets, or known attackers).
- ICMP validation failed ("ICMP blocked - unable to validate"), suggesting potential network restrictions or firewalls.
- Historical data (June 2026) shows no persistent malicious activity.
3. Behavioral Insights:
- DNSSEC validation is enabled, and no DNSBL listings were found.
- No open ports, TLS certificates, or HTTP services detected.
- Traceroute indicates transit through Comcast networks but timed-out hops.
Recommendations:
- Monitor for anomalies: Track changes in network behavior or new threat indicators (e.g., unexpected DNS activity, port openings).
- Verify ownership: Confirm Microsoft's use of this IP via internal records or Microsoft's public IP ranges.
- Network segmentation: Ensure this IP is appropriately segmented in your environment, given its association with a large cloud provider.
- Update WAF rules: If this IP is part of a public-facing service, update firewall/WAF rules to reflect its legitimate traffic patterns.
Conclusion:
This IP is likely a legitimate Microsoft Azure asset with no current malicious activity. However, its ambiguous geolocation and ICMP restrictions warrant further investigation to rule out misconfigurations or potential spoofing.
