-------------------------------------

             Summary: Mesos claims an IP belongs to the overlay network, even though it doesn't.
                 Key: MESOS-5840
                 URL: https://issues.apache.org/jira/browse/MESOS-5840
             Project: Mesos
          Issue Type: Bug
          Components: network
            Reporter: Gastón Kleiman


Using DC/OS' IPAM module, we attempted to launch a Docker task using {{BRIDGE}} networking, while also requesting an IP in an overlay network through the {{NetworkInfo}} message.

The IP subnet for that overlay network is {{192.168.0.0/17}}, but the the IP in {{TaskStatus}} is the private Docker {{BRIDGE}} IP: {{172.17.0.3}}.

It is confusing/inconsistent that {{TaskStatus.NetworkInfo\[0\].name}} is still {{overlay-network}}, but the IP is not in the right subnet.
