title: Add static dns entry
body: <p>What's the equivalent of hosts files in windows ?</p>
  
  <p>I want to add a dns entry so 'sql1' is pointing to localhost.</p>
  
  <p>I tried adding sql1 127.0.0.1 to /etc/resolveconf/resolv.conf.d/base
  and then sudo service resolveconf restart, but it's not working.
  A ping to sql still gives me unknown host sql1.</p>
