We pick i.root-servers.net, one of the 13 root servers (1), and ask it about c0.cz and learn that cz is delegated to five name servers (2), so we ask f.ns.nic.cz where we learn that c0.cz is delegated to five name servers, including ns.gransy.com (3), so we ask that one and get the following answer:
C0.cz is a domain controlled by five domain name servers at gransy.com having a total of six IP numbers. Two of them are on the same IP network. C0.cz has one IP number (77.78.104.3), but the reverse is yurika.gransy.com.
