We pick b.root-servers.net, one of the 13 root servers (1), and ask it about ns1.cz and learn that cz is delegated to five name servers (2), so we ask f.ns.nic.cz where we learn that ns1.cz is delegated to two name servers, including hestia.ns1.cz (3), so we ask that one and get the following answer:
Ns1.cz is a domain controlled by two domain name servers at ns1.cz and ha-vel.cz having a total of three IP numbers. All three of them are on different IP networks.
