IP Intelligence Briefing: 139.144.26.48

Date: 2026-06-01

---

**1. Core Profile**

• Risk Score: 25 (Low Risk)
• Ownership: Owned by Linode (ASN 63949), a cloud infrastructure provider.
• Geolocation: Registered to the U.S., but geoPlausible is false due to RTT anomalies (observed RTT: 37ms vs. expected minimum 143ms for 7165km).
• Network Role: CloudCompute infrastructure (hosting, no residential/mobile attributes).
• Threat Indicators: No malicious activity detected (no indicators, blacklists, or campaigns).

---

**2. Observational History**

• 17 observations over 30 days:

- Geolocation inconsistencies: Multiple entries show U.S. country code ("US") but inconsistent RTT/latency values.

- DNSBL listing: Detected in 1 of 8 DNSBL checks (low severity).

- Network stability: BGP route stability flagged as unstable (routeChanges30d: 0, but isRouteStable: false).

• No persistent threats: ThreatObservationCount = 0, no malicious persistence.

---

**3. Network Relationships**

• Linked entities:

- Linode network (same ASN/organization).

- DNS hostname: `139-144-26-48.ip.linodeusercontent.com` (no malicious domain associations).

• No external connections: No subnets, certificates, or organizations tied to this IP.

---

**4. Subnet Neighborhood**

• Subnet: 139.144.26.48/24
• Neighbor data: No active/sibling IPs reported (neighborCount = 0).
• Abuse density: 0% (clean subnet).

---

**5. Key Anomalies**

• Geolocation mismatch: RTT values suggest a closer geographical location than the registered U.S. IP.
• DNSBL alert: Minor listing in 1 of 8 DNSBL checks (low risk).
• BGP instability: Route stability flags may indicate misconfiguration or network churn.

---

**6. Recommendations**

• Monitor geolocation consistency: Investigate RTT anomalies to rule out spoofing or misconfigured routing.
• Review DNSBL context: Check if the DNSBL listing is false positive or tied to Linode’s infrastructure.
• Validate BGP stability: Confirm route stability with Linode’s network team if critical services rely on this IP.

Conclusion: This IP is a low-risk Linode cloud instance with no direct malicious activity. However, geolocation inconsistencies and minor DNSBL alerts warrant further scrutiny for potential misconfigurations or spoofing.
