We pick h.root-servers.net, one of the 13 root servers (1), and ask it about vtc.com.vn and learn that vn is delegated to seven name servers (2), so we ask d.dns-servers.vn where we learn that vtc.com.vn is delegated to two name servers, including dns1.vtc.vn (3), so we ask that one and get the following answer:
Authoritative answer
vn. net. com.vn. vtc.vn. ripe.net. vtc.com.vn. dns2.vtc.vn. dns1.vtc.vn. dns-servers.vn. vtc-a62822bd373. c.dns-servers.vn. e.dns-servers.vn. root-servers.net. f.dns-servers.vn. a.dns-servers.vn. d.dns-servers.vn. b.dns-servers.vn. authdns.ripe.net. a.root-servers.net. h.root-servers.net. g.root-servers.net. m.root-servers.net. j.root-servers.net. d.root-servers.net. i.root-servers.net. l.root-servers.net. k.root-servers.net. f.root-servers.net. c.root-servers.net. b.root-servers.net. e.root-servers.net. cctld.authdns.ripe.net. vn.cctld.authdns.ripe.net.
