# 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
