When a Host::Discovered becomes a Host::Managed, I see this error:

Dhcp orchestration calls to_ip_address (for the boot server) which is delegated from nic to host but in the host scope it cannot resolve dns because the subnet is nil... if i move to_ip_address to nic::managed this issue seems fixed.
