IP Geolocation: How IP Address Location Data Works

IP geolocation is the process of mapping an IP address to a physical location using databases that correlate IP address ranges with geographic areas. These databases are compiled by aggregating data from regional internet registries (ARIN, RIPE, APNIC, LACNIC, AFRINIC), ISP routing announcements (BGP data), and ongoing measurement studies that observe where traffic from specific IP ranges originates.

Geolocation accuracy varies significantly by query type. Country-level accuracy is typically 95-99% for consumer IP addresses. City-level accuracy degrades to 50-80% because IP address allocation doesn't map cleanly to cities — a single ISP may serve a metro area from one address block, locating thousands of users to one city. Rural areas are often mislocated to the nearest major city served by the same ISP routing hub.

For corporate and cloud IPs, geolocation often reflects the organization's headquarters or data center location rather than end user location. VPN and proxy IPs are typically identified at the proxy server's location, not the user's. ASN (Autonomous System Number) data — which identifies the network operator — is much more reliable than city geolocation and is commonly used for network attribution, fraud detection, and traffic analysis.

Common Use Cases
1

Identify traffic source in server logs

Look up IPs from web server access logs to understand geographic distribution of visitors or identify unusual traffic sources.

2

Debug CDN and routing issues

Check which ASN and region an IP belongs to when diagnosing why CDN traffic is routing unexpectedly.

3

Security investigation

Identify the organization and network type associated with IPs seen in security alerts, spam reports, or access attempts.

4

Verify VPN or proxy location

Check the apparent geographic location and ISP of your own IP address when using VPN services.

How to Use
  1. 1

    Enter the IP address

    Type an IPv4 or IPv6 address in the input field. Click 'Use My IP' to automatically look up your own current IP address.

  2. 2

    View geolocation and network data

    Results display country, region, city, ISP/organization name, ASN, and connection type (residential, corporate, data center, mobile).

  3. 3

    Review additional details

    Expand to see timezone, coordinates, postal code, and reverse DNS hostname if available for the queried IP.

Features
  • IPv4 and IPv6 support

    Fully supports both address families — look up any public IPv4 or IPv6 address.

  • ASN and organization data

    Returns the Autonomous System Number and organization name, more reliable than city-level geolocation for network attribution.

  • Connection type classification

    Identifies whether the IP is residential, business, mobile, hosting/data center, or proxy/VPN based on routing classification.

  • My IP detection

    One-click lookup of your own current IP address — useful for verifying VPN location, checking your public IP, or confirming NAT behavior.
