# IP Pinger

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

## Installation

```bash
npm install
```

## Usage

Start the server:

```bash
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
