title: AWS ECS DNS resolution fails
body: <p>Inside my docker container, the route output is as follos:</p>
  
  <pre><code>Kernel IP routing table
  Destination     Gateway         Genmask         Flags Metric Ref    Use Iface
  default         ip-172-17-0-1.e 0.0.0.0         UG    0      0        0 eth0
  172.17.0.0      *               255.255.0.0     U     0      0        0 eth0
  </code></pre>
  
  <p>When I try to ping ip-172-17-0-1.e, I get the following:</p>
  
  <pre><code>ping: unknown host ip-172-17-0-1.e
  </code></pre>
  
  <p>Pinging the ip ping 172.17.0.1 works... I accepted all defaults in my task definition and my network mode is bridge. Whats going on?</p>
