We pick c.root-servers.net, one of the 13 root servers (1), and ask it about coto.net.br and learn that br is delegated to six name servers (2), so we ask f.dns.br where we learn that coto.net.br is delegated to two name servers, including eliot.uol.com.br (3), so we ask that one and get the following answer:
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, hereafter referred to as "name server group 1". Worth noting is that five of the domains that use name server group 1 point only to the IP number 200.221.8.80.
The name server borges.uol.com.br
There are several hundred of domains that use the name server borges.uol.com.br.
