We pick l.root-servers.net, one of the 13 root servers (1), and ask it about saude.pe.gov.br and learn that br is delegated to six name servers (2), so we ask d.dns.br where we learn that pe.gov.br is delegated to two name servers, including ns1.pe.gov.br (3), so we ask that one and get the following answer:
Saude.pe.gov.br is a domain controlled by two domain name servers at pe.gov.br. Both are on the same IP network. Incoming mail for saude.pe.gov.br is handled by four mail servers at trendmicro.com and pe.gov.br having a total of three IP numbers. There are four duplicated IP numbers. All three of them are on different IP networks.
