DNS delegation of uolk.net.br updated: May 23, 2013 7:48:23 PM
We pick a.root-servers.net, one of the 13 root servers (1), and ask it about uolk.net.br and learn that br is delegated to six name servers (2), so we ask e.dns.br where we learn that uolk.net.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 22.214.171.124 use the two name servers borges and eliot.uol.com.br together, hereafter referred to as "name server group 1". Worth noting is that six of the domains that use name server group 1 point only to the IP number 126.96.36.199.
The three name servers borges, charles and eliot.uol.com.br together
There are about seventy domains that use the three name servers borges, charles and eliot.uol.com.br together, hereafter referred to as "name server group 2".
