We pick f.root-servers.net, one of the 13 root servers (1), and ask it about picjuke.com and learn that com is delegated to 13 name servers (2), so we ask e.gtld-servers.net where we learn that picjuke.com is delegated to two name servers, including ns4.domainmanager.com (3), so we ask that one and get the following answer:
The two name servers ns3 and ns4.domainmanager.com together
There are several thousand of domains that use the two name servers ns3 and ns4.domainmanager.com together, hereafter referred to as "name server group 1".
A third of them point to the two IP numbers 23.23.210.22 and 74.86.197.160 together, hereafter referred to as "IP group 1", (example: exppedia.com, zuimez.com and heo.us ). Worth noting is that half of the host names that point to IP group 1 use name server group 1.
The name server ns3.domainmanager.com
There are several thousand of domains that use the name server ns3.domainmanager.com.
Half of them use name server group 1 (example: alilamanggis.com, qpda.com and lotionandlace.com ). Worth noting is that a third of the domains that use name server group 1 point to IP group 1.
