What is IP Address Lookup?
IP address lookup (also known as IP geolocation) is the process of finding the geographic location and other details associated with an IP address. When you enter an IP address into our lookup tool, we query multiple databases to retrieve information about that address, including its approximate physical location, the Internet Service Provider (ISP) that owns it, and the organization using it.
Every device connected to the internet has a unique IP address assigned by its ISP. This address serves as the device's identity on the internet, allowing data to be routed to and from it. IP lookup tools use databases maintained by Regional Internet Registries (RIRs) and geolocation providers to map these addresses to real-world locations.
What Information Can You Find?
Geographic Location
City, region/state, country, and approximate coordinates. Accuracy varies from city-level to within a few kilometers depending on the IP type.
ISP & Organization
The Internet Service Provider that owns the IP block and the organization or company currently using the address.
Timezone
The timezone associated with the IP's location, useful for scheduling and understanding when users are active.
Network Information
IP version (IPv4 or IPv6), ASN (Autonomous System Number), and other technical network details.
Common Uses for IP Lookup
Security & Fraud Prevention
Identify suspicious login attempts, detect potential fraud by checking if user locations match expected patterns, and investigate security incidents by tracing IP addresses.
Website Analytics
Understand where your website visitors come from geographically, helping you tailor content, language, and marketing efforts to specific regions.
Content Personalization
Deliver location-specific content, show local pricing, display relevant advertisements, and customize user experiences based on geographic location.
Network Troubleshooting
Diagnose network issues by identifying the location and owner of IP addresses appearing in logs, helping trace routing problems and connectivity issues.
Compliance & Licensing
Enforce geographic restrictions for content licensing, ensure regulatory compliance, and verify that users are accessing services from permitted locations.
Email Verification
Analyze email headers to identify the origin of messages, helping detect spam, phishing attempts, and verify the authenticity of communications.
Frequently Asked Questions
How accurate is IP geolocation?
IP geolocation accuracy varies depending on several factors. For most residential IP addresses, geolocation can identify the correct city about 50-80% of the time. Country-level accuracy is typically 95-99%. However, the technology has limitations:
- Mobile networks: Cell tower routing can make IPs appear in different cities than the actual user
- VPNs and proxies: These mask the true location, showing the server's location instead
- Corporate networks: Large organizations may route traffic through central locations
- ISP infrastructure: IP blocks may be registered to ISP headquarters rather than user locations
IP geolocation should be used for general insights, not precise location tracking.
Can I look up anyone's IP address?
You can look up any public IP address using our tool. However, finding someone's IP address in the first place typically requires:
- Running a website or server they connect to (IP appears in server logs)
- Receiving an email from them (IP may be in email headers)
- Direct network communication (peer-to-peer connections)
It's important to note that IP lookup only provides general location information, not personal details like name or exact address. Using IP information to harass or stalk individuals is illegal in most jurisdictions.
Why does the location shown seem wrong?
There are several reasons why IP geolocation might show an incorrect or unexpected location:
- Using a VPN: VPN services route your traffic through servers in other locations
- ISP routing: Your ISP may route traffic through infrastructure in a different city
- Mobile networks: Cellular providers often use IP addresses registered to regional hubs
- Outdated databases: Geolocation databases may not reflect recent IP reassignments
- Proxy servers: Corporate or educational networks often use centralized exit points

What's the difference between public and private IP addresses?
Public IP addresses are globally unique and routable on the internet. These are the addresses that our lookup tool can query, as they're registered in global databases and visible to external servers.
Private IP addresses (like 192.168.x.x, 10.x.x.x, or 172.16-31.x.x) are used within local networks and cannot be looked up externally. They're reused across millions of networks worldwide and are translated to public IPs by routers using NAT (Network Address Translation).
Our tool will notify you if you enter a private IP address, as no geolocation data is available for these addresses.
Is IP lookup legal?
Yes, looking up publicly available IP address information is legal in most jurisdictions. IP geolocation data is publicly available and commonly used for legitimate purposes like:
- Website analytics and traffic analysis
- Fraud prevention and security
- Content localization and personalization
- Network troubleshooting and diagnostics
However, using IP information to stalk, harass, or commit crimes against individuals is illegal. Additionally, some jurisdictions have data protection laws (like GDPR) that may require consent for certain uses of IP data in commercial applications.
