DNS delegation of i.hosei.jp updated: May 25, 2013 8:03:10 PM
We pick h.root-servers.net, one of the 13 root servers (1), and ask it about i.hosei.jp and learn that jp is delegated to seven name servers (2), so we ask d.dns.jp where we learn that hosei.jp is delegated to two name servers, including ns0.hosei.jp (3), so we ask that one and get the following answer:
I.hosei.jp is a domain controlled by eight domain name servers at hosei.ac.jp having a total of ten IP numbers. Some of them are on the same IP network. Incoming mail for i.hosei.jp is handled by two mail servers also at hosei.ac.jp. Both are on the same IP network.
