How It Works

Our IP lookup tool provides fast, accurate, and privacy-friendly insights in just a few simple steps.

🔍

Enter IP Address

Simply enter any IPv4 or IPv6 address in the search bar, or leave it blank to look up your own current IP automatically.

📊

Analyze Data

Our system retrieves geolocation, ISP details, network routing data, and security threat insights from multiple databases instantly.

✅

Make Informed Decisions

Use the data to enhance security, detect fraudulent traffic, troubleshoot network issues, or understand what your own IP reveals online.

Under the Hood — The Technical Process

Here is what happens when you perform a lookup:

IP detection — If you did not enter an IP, the server reads your IP from the CF-Connecting-IP HTTP header injected by Cloudflare, which carries the real client IP even when the request passes through Cloudflare's edge network.
API query — Your IP is sent from our server to the ipdata.co API, which queries its geolocation and threat-intelligence databases. This happens server-side — your browser never communicates directly with the data provider.
Data enrichment — The response includes geolocation data (derived from BGP routing tables and regional internet registry WHOIS records), ASN ownership data, and threat flags from curated blocklists.
Result rendering — The enriched data is returned to your browser and displayed in the results panel. Latitude and longitude coordinates are used to place a marker on an interactive map powered by Leaflet.js and OpenStreetMap.

Data Fields Explained

Here is what each field in the results means:

ASN (Autonomous System Number)

A globally unique number identifying the network that owns this IP address block. Large organizations like ISPs, cloud providers, and universities each have one or more ASNs.

ISP (Internet Service Provider)

The organization that operates the ASN — typically the company providing internet access to this IP's user, or the cloud/hosting provider if it is a server address.

Route (CIDR Block)

The IP network block (e.g., 203.0.113.0/24) that this address belongs to, as advertised in the global BGP routing table.

Calling Code

The international phone dialing prefix for the country associated with the IP (e.g., +1 for the United States, +44 for the United Kingdom).

Threat Flags

Boolean indicators derived from threat intelligence databases: VPN, proxy, Tor exit node, datacenter IP, known abuser, known attacker, bogon (reserved/invalid), and iCloud Private Relay.

Accuracy and Limitations

IP geolocation is accurate to the country level in approximately 99% of cases, and to the city level for roughly 80% of residential IPv4 connections. Accuracy varies by context:

VPN and proxy users will see the exit server's location, not their physical location.
Mobile carrier users may see the city where the carrier's infrastructure is located rather than where they actually are.
CGNAT users (those behind carrier-grade NAT) share a public IP with many other customers. The location shown reflects the carrier's regional hub.
Corporate networks using a NAT gateway will show the company's office or data-center IP rather than the individual employee's location.

Privacy

Lookups are not logged or stored on our servers. All API calls to the data provider are made server-side — your IP is never sent from your browser to any third-party service. The interactive map is rendered client-side using Leaflet.js with OpenStreetMap tiles; OpenStreetMap does not track individual users. We do not require any account or login.
