We pick c.root-servers.net, one of the 13 root servers (1), and ask it about flickr.biz and learn that biz is delegated to six name servers (2), so we ask e.gtld.biz where we learn that flickr.biz is delegated to five name servers, including ns2.yahoo.com (3), so we ask that one and get the following answer:
Flickr.biz is a domain controlled by five domain name servers at yahoo.com. All five of them are on different IP networks. Incoming mail for flickr.biz is handled by one mail server at .. We are missing the IP:s of one server: .. Flickr.biz has two IP numbers (68.180.206.184, 98.139.102.145). Both are on different IP networks.
The five name servers ns1, ns2, ns3, ns4 and ns5.yahoo.com together
Two thirds of the several thousand of domains that use name server group 1 point to the two IP numbers 68.180.206.184 and 98.139.102.145 together, hereafter referred to as "IP group 1", (example: yavatar.net, yahooshoppingcenter.net and datingsiteyahoo.com ). Worth noting is that three quarter of the host names that point to IP group 1 use name server group 1.
The IP number 68.180.206.184
There are several thousand of host names that point to the IP number 68.180.206.184.
