Client IP

Introduction

The Client IP tool displays your current client IP address. When you access the internet, your device is assigned a unique IP address that the target server can identify. This tool retrieves your real IP directly from the server side, supporting both IPv4 and IPv6 address formats.

This tool also serves as a demonstration of a "complex tool requiring PHP backend processing," showcasing how custom server-side logic can be embedded in a tool detail page.

How It Works

Client IP detection relies on source address information in HTTP requests. The server can read the REMOTE_ADDR variable to get the directly-connected client IP. When behind a reverse proxy (Nginx, Cloudflare, CDN), the real client IP is carried in X-Forwarded-For or CF-Connecting-IP headers.

This tool uses the framework's built-in getClientIp() method, which automatically handles proxy header priority logic for the most accurate result.

Use Cases

• Network debugging: quickly verify your egress IP address
• Proxy/VPN testing: confirm your proxy or VPN is working correctly
• Network diagnostics: troubleshoot connectivity issues
• Development testing: verify IP detection logic in your application

FAQ

Q: The displayed IP differs from what I see on other websites?

A: If you're using a VPN or proxy, different sites may show different egress IPs. This tool shows your true IP reaching our server.

Q: Does it support IPv6?

A: Yes. If your network uses IPv6, the tool will display an IPv6-formatted address.
