We pick j.root-servers.net, one of the 13 root servers (1), and ask it about h.kobe-u.ac.jp and learn that jp is delegated to seven name servers (2), so we ask d.dns.jp where we learn that kobe-u.ac.jp is delegated to three name servers, including melchior.kobe-u.ac.jp (3), so we ask that one and get the following answer:
H.kobe-u.ac.jp is a domain controlled by four domain name servers at kobe-u.ac.jp having a total of seven IP numbers. Some of them are on the same IP network. Incoming mail for h.kobe-u.ac.jp is handled by one mail server also at kobe-u.ac.jp.
