IP REPUTATION ANALYSIS IN OSINT

Using AbuseIPDB and IP2Location for Layered Intelligence

Published: 2026-05-18

WHY IP REPUTATION MATTERS

IP addresses appear constantly in OSINT work: server logs, email headers, phishing infrastructure, C2 callbacks, and leaked data sets. Knowing whether an IP belongs to a VPN provider, a Tor exit network, or has been reported for abuse changes how you interpret everything else you find.

OpenOSINT provides two complementary tools for this: search_abuseipdb for crowd-sourced abuse data and search_ip2location for enriched geolocation and infrastructure classification. Running both gives you a complete picture.

ABUSEIPDB — CROWD-SOURCED ABUSE REPORTS

The search_abuseipdb tool queries the AbuseIPDB v2 API. The database aggregates reports from security teams, honeypots, and network operators worldwide.

Key fields returned:

Field	What it means
Abuse Confidence Score	0–100%. Higher = more confirmed abuse reports
Total Reports	Number of individual abuse reports in the database
Country / ISP / Domain	Basic attribution data
Last Reported	Timestamp of most recent report

A warning is displayed when the confidence score exceeds 50%.

$ openosint abuseipdb 198.51.100.1

[AbuseIPDB] IP: 198.51.100.1
[AbuseIPDB] Abuse Confidence Score: 87%
[AbuseIPDB] Total Reports: 143
[AbuseIPDB] Country: US
[AbuseIPDB] ISP: Example ISP LLC
[AbuseIPDB] Last Reported: 2026-05-20T14:33:00+00:00
⚠️  HIGH ABUSE CONFIDENCE — flagged by AbuseIPDB

Required: ABUSEIPDB_API_KEY environment variable — register for a free key.

IP2LOCATION — ENRICHED GEOLOCATION & INFRASTRUCTURE

The search_ip2location tool (sponsored integration) queries the IP2Location.io API. Beyond standard geolocation it classifies the IP's infrastructure type.

Key fields returned:

Field	What it means
Country / Region / City	Physical location to city level
ISP / Domain / ASN	Network operator and autonomous system
Proxy / VPN / TOR	Infrastructure classification (Security Plan)
Datacenter	Whether hosted in a cloud or datacenter range
Threat	Aggregate threat classification

$ openosint ip2location 8.8.8.8

[IP2Location] Country: United States (US)
[IP2Location] City: Mountain View, California
[IP2Location] ISP: Google LLC
[IP2Location] ASN: AS15169 Google LLC
[IP2Location] VPN: No  |  Proxy: No  |  TOR: No
[IP2Location] Datacenter: Yes
[IP2Location] Threat: clean

Required: IP2LOCATION_API_KEY environment variable — get one here.

RUNNING BOTH TOOLS IN SEQUENCE

For any IP encountered during an investigation, running both tools gives you:

Hard abuse data — reports from real incidents (AbuseIPDB)
Infrastructure classification — is it a VPN, proxy, or datacenter? (IP2Location)
Full geolocation — city, ASN, ISP for corroboration

In the OpenOSINT REPL, the AI agent chains both tools automatically:

openosint > investigate 198.51.100.1

  → search_ip('198.51.100.1')
  → search_ip2location('198.51.100.1')
  → search_abuseipdb('198.51.100.1')

  Summary: This IP is hosted at Example ISP (US). AbuseIPDB shows
  143 reports with 87% abuse confidence. Last reported 4 days ago.
  High-risk — treat with significant suspicion.

PRACTICAL APPLICATIONS

Scenario	What to look for
Phishing investigation	Datacenter flag + high abuse score = likely bulk-send infrastructure
Attacker attribution	VPN/Tor flag = deliberate anonymisation layer
Log analysis	High abuse score for a connection source = credible threat
Infrastructure mapping	ASN + datacenter flag identifies hosting provider
