IP Lookup
Enter any IPv4 or IPv6 address to find its location, ISP, ASN, and network details.
What Is an IP Address Lookup?
An IP address lookup queries geolocation and network databases to return information associated with a specific IP address. Every device on the internet communicates using IP addresses — these are numeric identifiers assigned by Internet Service Providers. By analyzing the IP's network registration data, we can determine the approximate geographic location, the owning organization, and the type of connection.
Our lookup uses MaxMind GeoLite2 — an industry-standard local database — meaning your queries are processed entirely on our servers without being forwarded to third-party APIs. This ensures fast response times, privacy for your lookups, and consistent results.
What Data Does an IP Lookup Return?
The registered country and administrative region (state/province) for the IP block.
Approximate city-level location — accuracy varies by ISP and region (50–80%).
The Internet Service Provider or organization that owns the IP address block.
Autonomous System Number — identifies the network operator in BGP routing tables.
Approximate coordinates for the IP's registered location (not the user's exact address).
The IANA timezone associated with the IP's geographic region.
Common IP Lookup Use Cases
- →Security & Fraud Prevention: Verify user locations against billing addresses. Detect logins from unexpected countries or high-risk IP ranges.
- →Content Geo-Restriction: Serve country-specific content, comply with licensing restrictions, or redirect users to local versions of your service.
- →Network Troubleshooting: Identify the source of suspicious traffic, verify BGP routing, and diagnose connectivity issues.
- →Threat Intelligence: Investigate malicious IP addresses involved in spam, DDoS attacks, or unauthorized access attempts.
- →Marketing & Analytics: Understand visitor demographics, optimize ad targeting by region, and analyze traffic patterns by geography.
Frequently Asked Questions
What is an IP lookup?
An IP lookup is the process of querying a geolocation database to find information associated with an IP address. This includes the approximate geographic location (country, region, city), the Internet Service Provider (ISP), the Autonomous System Number (ASN), and sometimes organization details. IP geolocation databases map IP address ranges to known physical locations based on network registration data.
How accurate is IP geolocation?
IP geolocation accuracy varies by geographic granularity. Country-level accuracy is typically 95–99%. City-level accuracy ranges from 50–80% depending on the ISP and region. Accuracy is lower for mobile networks (IPs are assigned dynamically across large regions), VPNs and proxies (which show the server's location, not the user's), and corporate networks (which may route through headquarters IPs).
What is an ASN (Autonomous System Number)?
An ASN is a unique identifier assigned to a network or group of networks that share a common routing policy, typically managed by an ISP, university, corporation, or cloud provider. ASNs are used in BGP (Border Gateway Protocol) routing to direct traffic across the internet. Example: AS15169 belongs to Google, AS13335 belongs to Cloudflare.
Why might an IP show the wrong location?
IP location inaccuracies happen for several reasons: Mobile carrier IPs are assigned from regional pools that don't match the user's city. VPN and proxy users show the server's location. Large corporations route branch office traffic through headquarters. ISPs sometimes assign blocks from different regions. Satellite internet (Starlink) shows gateway locations, not the user's actual position.
Can I look up my own IP address?
Yes. Visit our home page and your current public IP is detected automatically. Alternatively, enter your IP address in the lookup tool above. Your public IP is the address your ISP assigns to your internet connection — all devices on your home network share this single public IP when accessing the internet.
What is the difference between IPv4 and IPv6?
IPv4 addresses use 32-bit numbers (e.g., 192.168.1.1) providing ~4.3 billion unique addresses. IPv6 uses 128-bit addresses (e.g., 2001:db8::1) providing an essentially unlimited pool. IPv4 exhaustion led to NAT (Network Address Translation) which allows multiple devices to share one public IP. IPv6 adoption is growing but IPv4 remains dominant for most internet traffic.
