IP Pinger

A simple Node.js web service that returns the client's IP address.

Installation

npm install

Usage

Start the server:

npm start

The service will run on port 3000 by default. Visit http://localhost:3000 to see your IP address.

Environment Variables

• PORT - The port to run the service on (default: 3000)

How it works

The service checks multiple sources to determine the client IP:

1. X-Forwarded-For header (for proxies/load balancers)
2. X-Real-IP header
3. Socket remote address
4. Connection remote address
