We pick l.root-servers.net, one of the 13 root servers (1), and ask it about uolk.com.br and learn that br is delegated to six name servers (2), so we ask a.dns.br where we learn that uolk.com.br is delegated to two name servers, including eliot.uol.com.br (3), so we ask that one and get the following answer:
The two IP numbers 200.147.3.138 and 200.147.35.138 together
All of the one host names that point to the two IP numbers 200.147.3.138 and 200.147.35.138 together, hereafter referred to as "IP group 1", use name server group 1.
The IP number 200.147.3.138
