IP Lookup

The IP Lookup tool identifies who owns an IP address, where it originates, and how it’s used by returning geolocation, ISP, ASN, reverse DNS, and reputation data. It helps you verify traffic, troubleshoot issues, and block threats. Use IP Lookup when investigating users, diagnosing network problems, or validating security events.

What is IP Lookup?

IP Lookup is a network utility that translates an IP address into actionable information such as city, region, country, time zone, Internet Service Provider (ISP), Autonomous System Number (ASN), reverse DNS hostname, and risk indicators like blacklist status. By turning a raw IPv4 or IPv6 address into human-readable context, it enables faster decisions in security, IT support, analytics, and compliance.

On Monkey Type, the IP Lookup tool centralizes this data into a clean, searchable report. Instead of juggling multiple services for WHOIS, geolocation, and reputation, you can enter an IP address and immediately see a consolidated profile with location lookup, network ownership, CIDR ranges, and more.

If you are asking “Who is behind this IP, where is it located, and can I trust it?”, the IP Lookup tool gives you an immediate, reliable answer. It’s designed for speed, clarity, and practical next steps.

Why Use IP Lookup?

Detect and block risky traffic: Identify known spam sources, compromised hosts, or suspicious VPN/proxy endpoints. Solution: Use IP Lookup to check blacklist status and threat signals before granting access.
Troubleshoot user issues: Confirm if latency or access errors correlate with a user’s ISP, region, or ASN. Solution: Tie incidents to network providers to route, escalate, or communicate effectively.
Validate compliance and geo-restrictions: Enforce location-based rules for licensing or privacy. Solution: Verify country and region via IP geolocation to comply with policy.
Investigate security events: Enrich logs during incident response with owner, reverse DNS, and CIDR data. Solution: Quickly determine if an IP belongs to a cloud provider, data center, or residential ISP.
Improve analytics quality: Separate internal, bot, or data-center traffic from real users. Solution: Use IP Lookup to classify IP sources and refine your reporting.

How to Use IP Lookup on Monkey Type

Open the IP Lookup tool on Monkey Type.
Enter an IPv4 or IPv6 address in the search field (for example, a user’s source IP from your logs).
Click Look Up to start the query. The tool resolves the IP and aggregates geolocation, ISP, ASN, and reputation data.
Review the results panel: country, region, city, time zone, coordinates (approximate), ASN/Organization, ISP, reverse DNS, CIDR range, and blacklist/reputation signals.
Expand advanced sections to see proxy/VPN indicators, data-center flags, and relevant WHOIS or abuse contacts when available.
Use the copy and export options to share findings with your team or attach to a ticket or incident.

Expected results: A structured profile for the IP address, including location, ownership, and risk indicators, ready for decision-making and documentation.

Key Features

Comprehensive IP profile: Geolocation, ISP, ASN, reverse DNS, CIDR range, and time zone in one view.
IPv4 and IPv6 support: Accurate parsing and lookup for modern and legacy addresses.
Reputation and blacklist checks: Quick indicators for potential spam, malware, or abuse associations.
Proxy/VPN and data-center hints: Detect likely anonymizers or hosting providers.
WHOIS and abuse contacts: Identify the responsible network and where to report misuse.
Export-ready output: Copy or download results for incident tickets, audits, and reports.
Fast, unified interface: Perform an IP Lookup without switching between multiple tools or tabs.

Best Practices & Tips

Corroborate high-stakes decisions: Use IP Lookup as one signal; confirm with additional logs, user context, or device fingerprints before blocking.
Check both IPv4 and IPv6: Dual-stack environments may surface different behaviors; always review the actual address used.
Watch for data-center patterns: Repeated traffic from hosting providers may indicate bots, scrapers, or compromised servers.
Leverage ASN intelligence: Group incidents by ASN to spot provider-level trends and streamline firewall rules.
Mind geolocation limitations: City-level accuracy can vary; rely on country/region for policy enforcement when precision is critical.
Track time zones and latency: Pair IP time zone with request timestamps to spot anomalies and triage performance issues.

Common Use Cases

Security triage: Enrich SIEM or SOC alerts by running an IP Lookup on suspicious sources and adding ASN/ISP details to cases.
Fraud prevention: Compare user-declared location with IP geolocation to flag mismatches and require step-up authentication.
Access control: Enforce region-based access or license restrictions using country and data-center indicators.
Abuse handling: Identify the abuse contact for spam or scraping reports and include reverse DNS and CIDR evidence.
Network troubleshooting: Diagnose routing or connectivity issues by correlating incidents with specific ISPs or ASNs.
Analytics hygiene: Exclude bot and internal traffic by classifying IPs tied to proxies, VPNs, or hosting providers.

Frequently Asked Questions

What information does the IP Lookup tool provide?

The IP Lookup tool returns geolocation (country, region, city), time zone, ISP, ASN, reverse DNS, CIDR, and reputation indicators such as blacklist or proxy/VPN hints. It can also surface WHOIS ownership and abuse contacts when available.

How accurate is IP geolocation?

Country-level accuracy is typically high, while city-level precision can vary by provider and network type. Mobile carriers, VPNs, and enterprise NATs may reduce accuracy. Use IP Lookup with additional context for critical decisions.

Does IP Lookup work with IPv6 addresses?

Yes. The IP Lookup tool supports both IPv4 and IPv6, providing the same core details—geolocation, ISP, ASN, and reputation—when data is available.

Can IP Lookup detect VPNs or proxies?

It can flag likely proxies, VPNs, or data-center IPs using known ranges and patterns. However, anonymization services evolve, so treat results as indicators rather than absolute proof.

How do I use this on Monkey Type?

Open the IP Lookup tool on Monkey Type, enter the IP address, and click Look Up. You will receive a consolidated profile you can copy or export. Monkey Type streamlines investigations by putting IP ownership, location, and risk signals in one place.
