It is a server that accepts DNS queries for this service from the Internet. If you are using the premium plan, DNS servers provided by the partnering DNS provider are also included. You can use a Managed DNS Server as the primary name server or secondary name server, whichever you prefer.

A different Managed DNS Server is assigned for each contracted zone. You can check which Managed DNS Servers are assigned to the contracted zones from the "Zone Information" column on the control panel’s "Record Management" screen. Servers that take on zone transfer and DNS NOTIFY are different to Managed DNS Servers. Note that if you use such servers by linking them to the primary or secondary name server that you have prepared, you will need to configure settings that are different to those for Managed DNS Servers.
