Bug Description
The default is "grab all" which is great for convenience and can be configured to be differently by argument -I (interface) or interface commands in the config.
Currently it is "too" open on that.
I see it trying to bing link local addresses for each of the KVM guests I spawn.
They get virtual network devices and due to that ntp sees it tries to bind and fails.
