## THREAT INTELLIGENCE NARRATIVE

Target 103.176.21.84 is infrastructure-grade IP assigned to Vu Anh Tuan, a Vietnamese telecommunications entity. The low risk score (25) and absence of threat indicators support classification as benign infrastructure. The reverse DNS entry "Gravity.hire.uk.com" suggests potential international routing or multi-domain infrastructure deployment, though forward resolution remains unconfirmed.

DNSSEC validation is active, indicating security-conscious infrastructure operations. The absence of open services and the firewalled status are consistent with reserved or internal use cases. The single DNSBL listing requires attention but does not constitute a confirmed abuse indicator.

---

## RECOMMENDED ACTIONS

• Monitoring: Standard baseline monitoring recommended
• Firewall: No restrictive rules required; allow-list or monitor as normal
• Threat Intel: No blocking required
• Investigation: Not warranted at this time
• Correlation: Monitor for related IPs if unusual activity emerges

## CONCLUSION

IP 103.176.21.84 represents low-risk Vietnamese network infrastructure with no active threat indicators. The address shows stable ownership patterns and no evidence of malicious activity. SOC analysts may treat this as benign infrastructure requiring standard monitoring protocols.
