# INTELLIGENCE BRIEFING: 79.145.173.214/32

Classification: HIGH RISK — Mobile Carrier Dynamic IP

Date: 2026-07-25

Risk Score: 80/100

## EXECUTIVE SUMMARY

IP 79.145.173.214 is a high-risk (80/100) dynamic residential/mobile IP address assigned to Telefonica de Espana SAU (AS3352, RIMA). The IP is associated with a dynamic residential broadband connection and has been flagged by 4 out of 8 DNS blacklists. Despite a clean neighborhood profile (abuse density: 0), the elevated risk score warrants defensive monitoring and potential blocking.

## OWNERSHIP & NETWORK CLASSIFICATION

• ASN: 3352 (Administradores Telefonica de Espana)
• Organization: RIMA (Telefonica de Espana SAU)
• CIDR Block: 79.144.0.0/14

## DEFENSIVE RECOMMENDATIONS

Immediate Actions:

1. Increase logging verbosity for traffic from this IP

2. Consider blocking at perimeter firewall (see rules below)

3. Monitor for pattern changes (risk persistence)

Firewall Rules:

```bash

# iptables

iptables -A INPUT -s 79.145.173.214 -j DROP

# nftables

nft add rule inet filter input ip saddr 79.145.173.214 drop

# nginx

deny 79.145.173.214;

# Cloudflare WAF

{"description":"Block 79.145.173.214 — IPDebrief risk score 80","action":"block","filter":{"expression":"ip.src eq 79.145.173.214"}}

# AWS WAF

{"Addresses":["79.145.173.214/32"],"Description":"IPDebrief risk 80"}

```

## ANALYST NOTES

• False Positive Risk: Moderate — Dynamic residential IPs frequently appear on DNSBLs due to shared infrastructure abuse.
• Contextual Signal: High risk score (80) despite clean neighborhood (abuse density: 0). Consider traffic patterns before blocking.
• Mobile Carrier Attribution: Confirmed as Movistar LTE/5G connection (Spain operator). US geolocation may be routing artifact.
• Recommendation: Monitor for ≥3 incidents before permanent blocking. Implement rate limiting if blocking is not feasible.
