To get the hostname in a Django application, you can retrieve it from the request object in your views. The `request` object contains various details about the current HTTP request, including the hostname.

Here's a simple example of how to get the hostname in a Django view:

1. **Basic View Example**:
   ```python
   from django.http import HttpResponse

   def my_view(request):
       # Get the hostname from the request
       hostname = request.get_host()
       return HttpResponse(f"Hostname: {hostname}")
   ```

   In this example, `request.get_host()` is used to retrieve the hostname.

2. **Considerations for HTTP/HTTPS**:
   If your application is running behind a proxy or load balancer (like in many production setups), the `request.get_host()` might not return the correct result if the proxy doesn't set the appropriate headers. To handle such cases, ensure your proxy sets the `X-Forwarded-Host` header.

3. **Using `request.META`**:
   Alternatively, you can access lower-level HTTP header information through `request.META`, a Python dictionary containing all available HTTP headers. The host can sometimes be retrieved using `request.META['HTTP_HOST']`, but this is less reliable and not recommended for general use over `request.get_host()`.

4. **Middleware for Hostname**:
   If you need to access the hostname in many views, consider writing a middleware that adds the hostname to the request object. This way, you can easily access it in any view without repeating the extraction logic.

5. **Security Note**:
   Be cautious when using the hostname obtained from the request, especially if you're using it to construct URLs or in security mechanisms. It can be susceptible to HTTP Host header attacks if not validated properly.

Remember, `request.get_host()` will give you the host and possibly the port (like `example.com:8000`). If you need just the domain part without the port, you might need to parse the result accordingly.
