We pick m.root-servers.net, one of the 13 root servers (1), and ask it about clubeuol.com and learn that com is delegated to 13 name servers (2), so we ask a.gtld-servers.net where we learn that clubeuol.com is delegated to two name servers, including borges.uol.com.br (3), so we ask that one and get the following answer:
The three name servers borges, charles and eliot.uol.com.br together
There are more than hundred domains that use the three name servers borges, charles and eliot.uol.com.br together (but not thomas.uol.com.br ), hereafter referred to as "name server group 1".
Half of those point only to the IP number 200.147.3.199 (example: vmb.com.br, bol.com.br and tvcaras.com.br ). Worth noting is that more than one in seven of the host names that point only to the IP number 200.147.3.199 use name server group 1.
