DNS delegation of uolka.com.br updated: Jun 19, 2013 10:32:12 PM
We pick f.root-servers.net, one of the 13 root servers (1), and ask it about uolka.com.br and learn that br is delegated to six name servers (2), so we ask c.dns.br where we learn that uolka.com.br is delegated to two name servers, including eliot.uol.com.br (3), so we ask that one and get the following answer:
Eight of the nine host names that point only to the IP number 18.104.22.168 use the two name servers borges and eliot.uol.com.br together, hereafter referred to as "name server group 1". Worth noting is that eight of the domains that use name server group 1 point only to the IP number 22.214.171.124.
The three name servers borges, charles and eliot.uol.com.br together
