------------------------------------
First time submitting - Is there something left for me to do to close this out?
> CNI should not store subnet of address in NetworkInfo
> -----------------------------------------------------
>
> Key: MESOS-5453
> URL: https://issues.apache.org/jira/browse/MESOS-5453
> Project: Mesos
> Issue Type: Bug
> Reporter: Dan Osborne
> Assignee: Dan Osborne
> Labels: mesosphere
> Fix For: 0.29.0
>
>
> When the CNI isolator executes the CNI plugin, that CNI plugin will return an
> IP Address and Subnet (192.168.0.1/32). Mesos should strip the subnet before
> storing the address in the Task.NetworkInfo.IPAddress.
> Reason being - most current mesos components are not expecting a subnet in
> the Task's NetworkInfo.IPAddress, and instead expect just the IP address.
> This can cause errors in those components, such as Mesos-DNS failing to
> return a NetworkInfo address (and instead defaulting to the next configured
> IPSource), and Marathon generating invalid links to tasks (as it includes /32
> in the link)
