IP Intelligence Briefing: 147.15.15.226
Date: 2026-06-07
**Profile Summary**
- Risk Score: 30 (Low Risk)
- Provider: Oracle Corporation (ASN 31898)
- Geolocation: Registered to the U.S., but geolocation data indicates São Paulo, Brazil (potential inconsistency).
- Network Role: Oracle Cloud infrastructure (CloudCompute).
- Services: HTTP, HTTPS, SSH, HTTP-alt. TLS certificate is self-signed.
**Threat Indicators**
- No malicious indicators, abuse reports, or blacklist entries.
- No known attacker associations or spam sources.
**Observation History**
- Stable over 30 days: No significant changes in geolocation, DNS, or threat signals.
- Single observation record (likely a test or static asset).
**Relationships**
- Linked to Oracleβs ASN 31898 and multiple subnets labeled "ORACLE-4."
- No external hostnames or certificates associated.
**Neighborhood Analysis**
- Subnet 147.15.15.226/24 shows no active neighbors or abuse density.
- Isolated IP with no sibling IPs reported.
**Actionable Insights**
1. Geolocation Discrepancy: Investigate the U.S. registration vs. São Paulo location. Could indicate misconfigured geolocation data or a false positive.
2. Self-Signed Certificate: Monitor for potential misconfigurations or internal test environments.
3. Low Risk but Isolated: No immediate action required, but maintain monitoring for unexpected changes.
Recommendation: No firewall rules or blocking recommended. Focus on verifying geolocation accuracy and ensuring TLS configurations align with Oracleβs security policies.
