SUBNET CONTEXT (207.46.13.0/24)
The parent /24 subnet requires contextual awareness:
- Abuse Density: 0.2258 (moderate)
- Subnet Classification: Mixed
- Total Siblings: 31
- Active Siblings: 12
- Threat Siblings: 7
- Risk Distribution: 0 high-risk, 2 medium-risk, 29 low-risk
While the target IP is benign, the subnet environment contains elevated activity with 7 threat-identified siblings. Security teams should monitor the broader /24 for correlated malicious activity.

OBSERVATION HISTORY
Analysis of 25 historical observations indicates:
- Recent Activity: DNS resolution activity for msn.com domains (June 2026)
- Routing: Stable BGP routing through AS8075 (Microsoft)
- Persistence: No persistent malicious behavior observed
- Threat Persistence: Zero threat observation count
- Ownership Changes: None detected
The IP has maintained consistent operational patterns without evidence of malicious evolution.
---
RELATIONSHIP MAPPING
The IP maintains associations with:
- DNS Hostnames: msnbot-207-46-13-155.search.msn.com
- Network Segment: MICROSOFT-GLOBAL-NET
- Control Plane: Origin ASN 8075, AS path 49788 β 8075
Relationships confirm legitimate Microsoft enterprise infrastructure integration.

RECOMMENDATIONS FOR SECURITY OPERATIONS
1. Allow Traffic: The IP represents legitimate Microsoft search crawler activity. No blocking required.
2. Monitor Subnet: While the target IP is benign, monitor the 207.46.13.0/24 subnet for the 7 threat-sibling IPs. Notable high-risk addresses include 207.46.13.83 and 207.46.13.102 (risk score 50).
3. Baseline Behavior: Establish baseline for Microsoft msnbot traffic patterns to distinguish from potential spoofing attempts.
4. Geolocation Validation: Multiple geolocation sources confirm US presence, but ICMP validation was blocked during testing.
