We pick b.root-servers.net, one of the 13 root servers (1), and ask it about tvuol.com.br and learn that br is delegated to six name servers (2), so we ask b.dns.br where we learn that tvuol.com.br is delegated to two name servers, including eliot.uol.com.br (3), so we ask that one and get the following answer:
Tvuol.com.br is a domain controlled by two domain name servers at uol.com.br. Both are on different IP networks. Incoming mail for tvuol.com.br is handled by two mail servers also at uol.com.br. Both are on different IP networks. Tvuol.com.br has two IP numbers (200.147.3.199, 200.221.2.64). Both are on different IP networks.
