This site does more than answer “what is my IP.” It shows how your request appears to the server and, where available, how upstream proxies and CDNs identify the original client address.
Public IP address detection
Your public IP address is the address visible to external internet services. Depending on your network setup, it may reflect your router, ISP, VPN endpoint, corporate gateway, cloud egress point, or another upstream address.
Why multiple IP values can appear
In modern deployments, the server may receive a direct socket address and also receive one or more forwarded headers from reverse proxies or edge services. That is why the page checks fields such as remote_addr, X-Real-IP, X-Forwarded-For, Forwarded, and provider-specific headers.
Why this is useful
- Verify whether a reverse proxy is passing the correct client IP
- Compare VPN egress behavior against what the application sees
- Inspect CDN-specific client IP headers
- Troubleshoot firewall allowlists and upstream access controls
- Review the exact request headers services on the internet are receiving
Browser and request information
The page also displays browser, platform, engine, language, and related client-side details to help correlate what the browser reports with what a website on the internet receives.
Who this is for
This tool is useful for developers, system administrators, network engineers, security teams, anyone troubleshooting client connectivity through layered infrastructure or persons interesting in what data websites can collect about them.
