We pick l.root-servers.net, one of the 13 root servers (1), and ask it about daklak.vn and learn that vn is delegated to seven name servers (2), so we ask vn.cctld.authdns.ripe.net where we learn that daklak.vn is delegated to six name servers, including c.dns-servers.vn (3), so we ask that one and get the following answer:
Daklak.vn is a domain controlled by six domain name servers at dns-servers.vn having a total of eight IP numbers. All eight of them are on different IP networks.
