title: How Avahi dnsconfd works?
body: <p>I see that avahi-dnsconfd achieve to handle dns request from the browser without being listed in /etc/resolv.conf. I think that it's part of the dns resolution spec to check whether or not localhost can answer the query first. </p>
  
  <p>The problem is that, it looks like, there's nobody on port 53. So how does avahi catch dns lookups and answer it ?</p>
