Once the zone is added into Dyn’s Managed DNS, you will need to define a node for each host (IP Address) you want contained within the zone. All changes are staged until they are published, including new zone creation and adding nodes to the zone.  After you make the changes to your zone, you will need to publish the new information in order for Dyn’s edge nameservers to be aware of the updates.
