We pick g.root-servers.net , one of the 13 root servers (1), and ask it about www.bol.com.br and learn that br is delegated to six name servers (2), so we ask f.dns.br where we learn that bol.com.br is delegated to three name servers, including borges.uol.com.br (3), so we ask that one where we see a CNAME from www.bol.com.br to amazonas.uol.com.br , so we have to start all over again. We already know that b.dns.br is authoritative for br (4) and ask it about amazonas.uol.com.br and learn that uol.com.br is delegated to three name servers (5), so we ask borges.uol.com.br and get the following answer:

The two IP numbers 200.147.3.199 and 200.147.35.224 together There are about eighty host names that point to IP group 2 .
One quarter of those use mail server group 1 . One quarter of them use name server group 1 . Every fifth of them use name server group 3 (example: bundasex.com.br ).
