We pick m.root-servers.net, one of the 13 root servers (1), and ask it about bol.cz and learn that cz is delegated to five name servers (2), so we ask f.ns.nic.cz where we learn that bol.cz is delegated to two name servers, including ns1.vshosting.cz (3), so we ask that one and get the following answer:
Bol.cz is a domain controlled by two domain name servers at vshosting.cz having a total of four IP numbers. All four of them are on different IP networks. Bol.cz has one IP number (93.185.96.116), but the reverse is tyden-www.vshosting.cz.
