IPIP Lookup

Complete IP Address Guide

An IP (Internet Protocol) address is a unique number that identifies a device on the internet. This tool instantly shows your public IP address along with geolocation (city, country), ISP, and timezone — all in one place. Useful for verifying VPN connections, debugging location-based services, and diagnosing network issues.

Public IP vs Private IP

A public IP is globally unique and visible on the internet. A private IP is used only within your local network behind a router. Most home and office computers share a single public IP through NAT. This tool always shows the public IP seen by the outside world.

IPv4 vs IPv6

• IPv4: 32-bit, four dot-separated numbers (e.g. 203.0.113.1), ~4.3 billion addresses
• IPv6: 128-bit, colon-separated hex (e.g. 2001:db8::1), virtually unlimited
• Most ISPs now run dual-stack (both IPv4 and IPv6 simultaneously)

IP Geolocation: How It Works and Its Accuracy

IP geolocation estimates country and city from IP range registrations and ISP data. Country-level accuracy is 95%+, but city-level drops to 50-80%. VPNs, mobile networks, and corporate leased lines can cause significant offsets.

VPN and Proxy Detection

• Enable VPN and refresh — the tool will show the VPN server's IP and location
• If the displayed country differs from your actual location, your VPN is working
• The Org field often reveals the VPN provider's name
• Useful for confirming the exit node when bypassing regional restrictions

How to Use

1. Your public IP and location are fetched automatically on page load.
2. Click the copy button to copy the IP to your clipboard.
3. Click Refresh to fetch the latest information again.

Lookups use the public ipinfo.io API. This tool does not store any data on its own servers.
