# IP Intelligence Briefing: 54.39.0.245

## Executive Summary

IP address 54.39.0.245 presents a moderate risk profile (risk score: 40) associated with OVH cloud hosting infrastructure in Canada. While the IP itself shows no active malicious indicators, it resides within a high-abuse-density subnet (0.6992 abuse density) with 179 of 256 total IPs classified as threat siblings. SOC teams should monitor for potential abuse correlation but maintain contextual awareness of the broader subnet environment.

## Infrastructure Profile

## Threat Assessment

• Active Threat Indicators: None detected
• Known Attacker Status: Not flagged
• Tor Exit Node: No
• Spam Source: No
• Blacklist Count: 0
• DNSBL Listings: 1 of 8 total lists

The IP is not currently associated with known campaigns or threat feeds. No open ports or services were detected (firewalled/no services configuration).

## Neighborhood Analysis

The parent subnet (54.39.0.0/24) exhibits elevated abuse characteristics:

• Abuse Density: 0.6992 (high_abuse classification)
• Total Siblings: 256
• Active Siblings: 220
• Threat Siblings: 179
• Inherited Risk Score: 27
• Risk Distribution: 0 high-risk, 66 medium-risk, 34 low-risk IPs

This contextual finding suggests the broader infrastructure may host multiple entities, warranting broader subnet-level monitoring.

## Temporal Indicators

Observation history (18 signals) indicates recent listing activity as of 2026-06-26 with high-severity classifications. Control plane analysis shows stable routing with no BGP prefix changes in the past 30 days. DNSSEC validation is active.

## Recommended Actions

Based on risk profile, the following firewall rules are recommended:

```bash

# iptables

iptables -A INPUT -s 54.39.0.245 -j DROP

# nftables

nft add rule inet filter input ip saddr 54.39.0.245 drop

# nginx

deny 54.39.0.245;

# Cloudflare WAF

{"description":"Block 54.39.0.245 — IPDebrief risk score 40", "action":"block", "filter":{"expression":"ip.src eq 54.39.0.245"}}

# AWS WAF

{"Addresses":["54.39.0.245/32"], "Description":"IPDebrief risk 40"}

```

## Intelligence Context

The PTR hostname (proxy-ca004-san245.ahrefs.net) suggests association with Ahrefs infrastructure, a legitimate SEO analytics platform. However, the high abuse density of the parent subnet indicates potential for compromised or misconfigured co-located resources. SOC analysts should:

1. Monitor for lateral correlation with other 54.39.0.0/24 addresses

2. Evaluate traffic patterns against known Ahrefs services

3. Consider subnet-level blocking if multiple threat indicators emerge

4. Maintain awareness that 179 threat siblings exist within this /24

Assessment: Moderate risk IP requiring contextual subnet monitoring. No immediate blocking required unless corroborating threat intelligence indicates active malicious use.
