We pick m.root-servers.net, one of the 13 root servers (1), and ask it about e.z-z.jp and learn that jp is delegated to seven name servers (2), so we ask a.dns.jp where we learn that z-z.jp is delegated to two name servers, including ns2.dns.ne.jp (3), so we ask that one and get the following answer:
E.z-z.jp is a domain controlled by two domain name servers at dns.ne.jp. Both are on different IP networks. Incoming mail for e.z-z.jp is handled by one mail server at z-z.jp. E.z-z.jp has one IP number (182.48.17.157), which also has a corresponding reverse pointer.
