# IP Intelligence Briefing: 148.113.130.189/32
Classification: Moderate Risk / High-Abuse Subnet Environment
Risk Score: 40/100
Last Updated: 2026-06-20
## Executive Summary
IP 148.113.130.189 is a cloud-hosted infrastructure endpoint associated with OVH network (ASN 16276). The IP operates within a high-abuse density subnet (68.75% abuse density) and presents a moderate risk profile. While no direct threat indicators or active campaigns were detected, the operational environment warrants defensive consideration.
## Network and Infrastructure Profile
| Attribute | Value |
|---|---|
| **ASN** | 16276 (OVH) |
| **Organization** | Dmytro, Ahrefs Pte Ltd |
| **Infrastructure Type** | Cloud Compute / Hosting |
| **CIDR Block** | 148.113.130.0/24 |
| **Network Classification** | Firewalled / No Services Open |
## Geolocation Discrepancy Analysis
Critical geolocation validation failure detected:
- Claimed Location: Singapore
- Observed RTT: 26ms average
- Geographically Implausible: Minimum possible RTT for claimed distance (6,082 km) is 121.6ms
- Validation Status: GEO_PLAUSSIBLE = FALSE
This discrepancy indicates the IP is likely being misreported or is operating from a location different than claimed.
## Threat Indicators Assessment
| Indicator | Status |
|---|---|
| Known Attacker | No |
| Tor Exit Node | No |
| Spam Source | No |
| Blacklist Count | 0 |
| Threat Feeds | None Detected |
Note: No active threat indicators detected, though the operational context (high-abuse subnet) requires monitoring.
## Subnet Environment Analysis
The parent subnet /24 exhibits elevated abuse characteristics:
- Active Siblings: 209 out of 256 IPs
- Threat-Scored Siblings: 176 IPs
- Subnet Risk: 68.75% abuse density (classified as HIGH_ABUSE)
- Inherited Risk Score: 27/100
This indicates the IP operates in an environment with significant malicious activity, suggesting the possibility of compromised co-hosted infrastructure.
## DNS Resolution
- PTR Hostname: proxy-ca009-san189.ahrefs.net
- Resolved Domain: ahrefs.net
- Forward Resolution: Single record confirmed
## Recommended Security Actions
Defensive blocking is recommended due to moderate risk score and high-abuse subnet environment:
| Platform | Recommended Rule |
|---|---|
| iptables | `iptables -A INPUT -s 148.113.130.189 -j DROP` |
| nftables | `nft add rule inet filter input ip saddr 148.113.130.189 drop` |
| Cloudflare WAF | Block IP with expression: `ip.src eq 148.113.130.189` |
| AWS WAF | Block address: 148.113.130.189/32 |
## Intelligence Assessment
This IP should be treated as a potential risk due to:
1. Operation in a high-abuse density subnet (68.75%)
2. Geolocation validation failure indicating possible obfuscation
3. Cloud-hosted infrastructure commonly utilized by both legitimate and malicious actors
Recommendation: Apply defensive blocking measures. Monitor for any behavioral changes or emergence of threat indicators. Consider blocking the broader /24 subnet if operational requirements permit, given the 68.75% abuse density.
