- Network Role: Cloud compute instance (OVH), no CDN/VPN/Proxy flags.
---
**2. Threat Indicators**
- No Malicious Activity: No DNS-based threats, spam, or known attacker associations.
- DNS Associations: Linked to `proxy-uk004-san53.ahrefs.net` (likely legitimate Ahrefs infrastructure).
- Subnet Abuse Density: Subnet 198.244.183.0/24 shows high abuse density (0.5078), with 130 threat siblings (high-risk neighbors).
---
**3. Observation History**
- Recent Activity (2026-06-08):
- DNS resolution for `ahrefs.net` (valid domain).
- Geolocation inferred via multi-signal analysis (London, UK).
- Network classification as "high_abuse" for subnet.
- Stability: Subnet route stability is low (route changes in last 30 days).
---
**4. Relationships**
- Network: Linked to OVH network (ASN 16276).
- DNS: Direct association with Ahrefs’ domain (`ahrefs.net`).
- No Malicious Campaigns: No known campaigns or malicious certificates tied to the IP.
---
**5. Neighborhood Analysis**

- Active Neighbors: 85 IPs (130 flagged as high-risk).
- Risk Distribution:
- High Risk: 0 IPs (none directly tied to this IP).
- Medium Risk: 93 IPs (subnet-wide).
- Low Risk: 7 IPs.
- Inherited Risk: 20% (subnets with high abuse density).
---
**6. Recommendations**
- Monitor Subnet: The subnet has a high abuse density; investigate traffic patterns from high-risk neighbors.
- Verify DNS: Confirm that `proxy-uk004-san53.ahrefs.net` is legitimate Ahrefs infrastructure.
- Block High-Risk Neighbors: Consider restricting traffic from high-risk IPs in the subnet if they are not part of expected traffic.
- No Immediate Action: The IP itself shows no direct malicious activity, but subnet-level risks warrant closer scrutiny.
