## Keep a track of client's IP address

Now that the portal was up and ready, Batman realised that the Joker was using the Gotham Police Dashboard too. So, he wanted to keep a track of the IP address of the client who was accessing his application. He used the following code to do so:


<Row>
<Col>
Batman scaled his application across multiple cores for better performance. He used the following command:
</Col>
  <Col sticky>

    <CodeGroup title="Request" tag="GET" label="/hello_world">

    ```python {{ title: 'untyped' }}  
    from robyn import Robyn

    app = Robyn(__file__)

    @app.get("/")
    async def h(request):
        return f"hello to you, {request.ip_addr}"

    ```

    </CodeGroup>
  </Col>
</Row>

Batman wondered about whether Robyn handlers can be dispatched to multiple processes.

Robyn showed him the way!
