We pick f.root-servers.net, one of the 13 root servers (1), and ask it about rosatel.mx and learn that mx is delegated to six name servers (2), so we ask i.mx-ns.mx where we learn that rosatel.mx is delegated to three name servers, including ns3.terra.com (3), so we ask that one and get the following answer:
Rosatel.mx is a domain controlled by two domain name servers at terra.com.br. Both are on different IP networks. Incoming mail for rosatel.mx is handled by one mail server at terra.com.
