We pick c.root-servers.net, one of the 13 root servers (1), and ask it about uolk.net and learn that net is delegated to 13 name servers (2), so we ask g.gtld-servers.net where we learn that uolk.net is delegated to two name servers, including eliot.uol.com.br (3), so we ask that one and get the following answer:
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 seven 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.
