We pick j.root-servers.net, one of the 13 root servers (1), and ask it about eu and learn that eu is delegated to six name servers (2), so we ask nl.dns.eu and get the following answer:
All of the two domains that use the name server nl.dns.eu use the six name servers cz, nl, si, uk, x and y.dns.eu together, hereafter referred to as "name server group 1", (example: .eu ).
The name server cz.dns.eu
