We pick c.root-servers.net, one of the 13 root servers (1), and ask it about saude.ba.gov.br and learn that br is delegated to six name servers (2), so we ask a.dns.br where we learn that ba.gov.br is delegated to four name servers, including cpu0020.prodeb.gov.br (3), so we ask that one and get the following answer:
Two of them point only to the IP number 200.187.60.69. Worth noting is that all of the host names that point only to the IP number 200.187.60.69 use name server group 1.
Two of them use only the mail server appliance2.ba.gov.br. Worth noting is that two of the domains that only use the mail server appliance2.ba.gov.br use name server group 1.
One of them point only to the IP number 200.187.60.34.
Two of the four domains that only use the mail server appliance2.ba.gov.br use name server group 1. Worth noting is that two of the domains that use name server group 1 use only the mail server appliance2.ba.gov.br.
All of the two host names that point only to the IP number 200.187.60.69 use name server group 1. Worth noting is that two of the domains that use name server group 1 point only to the IP number 200.187.60.69.
The IP number 200.187.60.69
There are two host names that point to the IP number 200.187.60.69.
All of those use name server group 1.
All of them point only to that ip number.
The four name servers cpu0034.ba.gov.br, cpu0020.prodeb.gov.br, riosena6.prodeb.gov.br and riosena7.…
