We pick d.root-servers.net, one of the 13 root servers (1), and ask it about cheapjohns.biz and learn that biz is delegated to six name servers (2), so we ask k.gtld.biz where we learn that cheapjohns.biz is delegated to two name servers, including yns2.yahoo.com (3), so we ask that one and get the following answer:
All of the several thousand of host names that point only to the IP number 67.195.61.65 use the two name servers yns1 and yns2.yahoo.com together, hereafter referred to as "name server group 1", (example: leyendecker.com, frybreadbabies.com and techcheckonline.com ). Worth noting is that three percent of the domains that use name server group 1 point only to the IP number 67.195.61.65.
The IP number 67.195.61.65
There are several thousand of host names that point to the IP number 67.195.61.65.
