We pick h.root-servers.net, one of the 13 root servers (1), and ask it about uolligado.net.br and learn that br is delegated to six name servers (2), so we ask e.dns.br where we learn that uolligado.net.br is delegated to two name servers, including eliot.uol.com.br (3), so we ask that one and get the following answer:
There are nine domains that only use the IPv4 number 200.221.8.80.
Eight of those are under the tld "br".
Eight of them use name server group 1. Worth noting is that eight of the domains that use name server group 1 use only the IPv4 number 200.221.8.80.
The primary name server eliot.uol.com.br only
There are several hundred of domains that use the primary name server eliot.uol.com.br.
More than one in eight of those use the three name servers borges, charles and eliot.uol.com.br together, hereafter referred to as "name server group 2", (example: assinecaras.com.br, vmb.com.br and bol.com.br ). Worth noting is that three quarter of the domains that use name server group 2 use the primary name server eliot.uol.com.br.
