We pick d.root-servers.net, one of the 13 root servers (1), and ask it about zipmail.com.br and learn that br is delegated to six name servers (2), so we ask c.dns.br where we learn that zipmail.com.br is delegated to four name servers, including thomas.uol.com.br (3), so we ask that one and get the following answer:
There are several hundred of host names that point to the IP number 200.147.3.199 only (but not 200.147.35.224 ).
One quarter of those use name server group 1 (example: glamurama.com.br ). Worth noting is that every fifth of the domains that use name server group 1 point to the IP number 200.147.3.199 only (but not 200.147.35.224 ).
More than one in seven of them use name server group 2 (example: assinecaras.com.br ). Worth noting is that half of the domains that use name server group 2 point to the IP number 200.147.3.199 only (but not 200.147.35.224 ).
