---

## Executive Summary

IP address 189.99.187.29 presents a low-risk profile with minimal threat indicators. The asset is classified as "Low Risk" with a risk score of 15. No active threat campaigns or malicious activity signatures have been detected. The IP is not associated with Tor exit nodes, known attackers, or spam sources. However, conflicting geolocation data and minimal operator scoring warrant continued observation.

## Ownership and Network Classification

• Origin ASN: AS26599 (TELEFÔNICA BRASIL S.A.)
• BGP Prefix: 189.98.0.0/15
• Registered Organization: TELEFÔNICA BRASIL S.A.
• RIR: LACNIC
• Network Role: Firewalled / No Services
• Infrastructure Type: Not cloud, CDN, proxy, or hosting infrastructure

The IP belongs to a major Brazilian telecommunications carrier. Control plane analysis indicates the origin ASN with stable route characteristics, though geographic consensus remains unresolved.

## Geolocation Assessment

Current Classification: US (US-NY)

Conflicting Signals: Brazil (BR) — Multiple geolocation sources indicate Brazilian territory (latitude: -22.83, -43.22 and -14.24, -51.93)

Assessment: Geographic data validation failed (geoPlausible: false). The .com.br reverse DNS record and LACNIC RIR registration strongly suggest Brazilian origin. Discrepancy between profile (US) and historical signals (BR) indicates potential geo-IP misattribution or multi-homed routing. Recommend treating this as Brazil-origin traffic pending further verification.

## Threat Indicators

No active threat indicators detected. The single DNSBL listing requires contextual review but does not elevate overall risk posture.

---

## DNS Analysis

• Reverse DNS: ip-189-99-187-29.user.vivozap.com.br
• Forward Resolution: Unconfirmed (forwardConfirmed: false)
• Hosted Domains: 0
• Email Authentication: SPF and DMARC not configured
• Domain: .com.br (Brazilian TLD)

The reverse DNS record points to a user-facing service under the vivozap.com.br domain, consistent with TELEFÔNICA BRASIL S.A. infrastructure. Forward resolution failure suggests the IP is not actively serving web services at this time.

---

## Service and Port Status

• Open Ports: None detected
• TLS Certificate: None
• HTTP Title: None
• Server Banner: None

No services are currently accessible. The network classification indicates "Firewalled / No Services," suggesting this IP is either in a non-service state or protected by strict firewall rules.

---

## Neighborhood Assessment

• Subnet: 189.99.187.29/24
• Abuse Density: 0
• Threat Siblings: 0
• High/Medium Risk Neighbors: 0

The /24 subnet shows no abuse activity and zero threat-adjacent IPs, indicating this is an isolated, non-abusive segment of the network.

---

## Temporal Analysis

• Threat Persistence Days: 0
• Ownership Changes: 0
• Average Ownership Duration: N/A
• Persistently Malicious: No

The IP shows no persistent malicious behavior over time. Ownership has remained stable with no changes recorded.

---

## Historical Observations (Last 15 Signals)

Recent signal history reveals:

• ASN 26599 (TELEFÔNICA BRASIL S.A.) consistently reported
• Geographic signals predominantly indicate Brazil (BR)
• Operator score: 0.1304 (Minimal)
• Multiple signal types including geolocation, ASN, and reputation scoring
• No escalation in threat indicators over observation period

---

## Recommended Actions

Current Risk: Low (Score: 15)

Firewall Rules: No specific rules recommended. Default allow/deny policies apply.

Note: Geographic attribution conflict requires verification. The .com.br domain and LACNIC registration indicate Brazil, but profile geolocation shows US. This discrepancy should be validated before making classification decisions.

## Conclusion

IP 189.99.187.29 is a low-risk telecommunications infrastructure IP belonging to TELEFÔNICA BRASIL S.A. (AS26599). No malicious activity, threat campaigns, or abuse indicators have been detected. The primary intelligence gap involves conflicting geographic data between profile (US) and historical signals (BR). Given the .com.br reverse DNS and LACNIC registration, Brazil origin is the most likely classification. SOC teams may treat this as benign Brazilian ISP infrastructure with minimal operational concern.
