This free IP checker shows more than just your public IP address. It also inspects forwarded headers, reverse-proxy and CDN client IP fields, browser details, and the full HTTP request headers received by the server.
If you are troubleshooting VPN routing, reverse proxies, Cloudflare, upstream applications, firewall rules, or client connection behavior, this page gives you more context than a basic “what is my IP” lookup.
Your public IP address is the identifier your network uses on the internet. This page helps you find your public IPv4 and IPv6 addresses and inspect how your connection appears through reverse proxies, CDNs, VPNs, and forwarded request headers.
Most IP checker pages only show a single detected address. This tool also surfaces multiple proxy-aware IP sources, browser and platform information, and the raw request headers that help explain how your traffic was presented to the application.
This inspector can reveal both IPv4 and IPv6-related client address information, depending on how the request reached the service and which headers were provided upstream. IPv6 is the newer protocol with a much larger address space, while IPv4 remains widely used across public internet connections.
If your traffic passes through Nginx, Cloudflare, Fly.io, Akamai, or another upstream proxy layer, the address shown by the socket may differ from the original client IP. Looking at multiple headers in one view makes it easier to validate whether your proxy chain is passing the correct client address to the application.
