title: What is the use of Docker 'host' and 'none' Networks?
body: <p>Trying to understand Docker Networks. Docker creates the following networks automatically:</p>
  <pre><code># docker network ls 
  NETWORK ID          NAME                DRIVER              SCOPE
  67b4afa88032        bridge              bridge              local               
  c88f997a2fa7        host                host                local               
  1df2947aad7b        none                null                local               
  </code></pre>
  <p>I understood that the <strong>bridge</strong> network represents the docker0 network present in all Docker installations, referring from the <a href="https://docs.docker.com/engine/userguide/networking/" rel="nofollow noreferrer">link.</a></p>
  <p>Can someone help me in understanding other networks, <strong>host</strong> and <strong>none</strong>, If possible with examples?</p>
