instruction: Create a comprehensive Dockerfile for networking applications with best practices
output: ```dockerfile
  from the Docker host (the container shares the host's
  networking namespace), and the container doesn't get its own IP-address allocated.
  For instance, if you run a container which binds to port 80 and you use host
  networking, the container's application is available on port 80 on the host's IP
  address.
  NoteGiven that the container does not have its own IP-address when using
  host mode networking, port-mapping doesn't
  take effect, and the -p, --publish, -P, and --publish-all option are
  ignored, producing a warning instead:
  
  WARNING: Published ports are discarded when using host network mode
  Host mode networking can be useful for the following use cases:To optimize performanceIn situations where a container needs to handle a large range of portsThis is because it doesn't require network address translation (NAT), and no "userland-proxy" is created for each port.The host networking driver is supported on Docker Engine (Linux only) and Docker Desktop version 4.34 and later.You can also use a host network for a swarm service, by passing --network host
  to the docker service create command. In this case, control traffic (traffic
  related to managing the swarm and the service) is still sent across an overlay
  network, but the individual swarm service containers send data using the Docker
  daemon's host network and ports. This creates some extra limitations. For instance,
  if a service container binds to port 80, only one service container can run on a
  given swarm node.Docker DesktopHost networking is supported on Docker Desktop version 4.34 and later.
  To enable this feature:Sign in to your Docker account in Docker Desktop.Navigate to Settings.Under the Resources tab, select Network.Check the Enable host networking option.Select Apply and restart.This feature works in both directions. This means you can
  access a server that is running in a container
