We pick a.root-servers.net, one of the 13 root servers (1), and ask it about godaddy.biz and learn that biz is delegated to six name servers (2), so we ask e.gtld.biz where we learn that godaddy.biz is delegated to three name servers, including cns1.secureserver.net (3), so we ask that one and get the following answer:
Godaddy.biz is a domain controlled by three domain name servers at secureserver.net having a total of six IP numbers. All six of them are on different IP networks. Incoming mail for godaddy.biz is handled by two mail servers also at secureserver.net having a total of three IP numbers. There are three duplicated IP numbers. Two of them are on the same IP network. Godaddy.biz has one IP number (97.74.104.201), but the reverse is corpweb-v101.prod.mesa1.secureserver.net.
