We pick e.root-servers.net, one of the 13 root servers (1), and ask it about uolligado.com.br and learn that br is delegated to six name servers (2), so we ask f.dns.br where we learn that uolligado.com.br is delegated to four name servers, including eliot.uol.com.br (3), so we ask that one and get the following answer:
All of the nine host names that point to the IP number 200.221.8.80 point only to that ip number.
The IP number 200.221.8.80 only
Eight of the nine host names that point only to the IP number 200.221.8.80 use the two name servers borges and eliot.uol.com.br together (but neither charles nor thomas.uol.com.br ), hereafter referred to as "name server group 1". Worth noting is that three of the domains that use name server group 1 point only to the IP number 200.221.8.80.
