DNS delegation of i.x0.com updated: May 22, 2013 4:40:34 AM
We pick i.root-servers.net, one of the 13 root servers (1), and ask it about i.x0.com and learn that com is delegated to 13 name servers (2), so we ask f.gtld-servers.net where we learn that x0.com is delegated to two name servers, including ns1.dns.ne.jp (3), so we ask that one and get the following answer:
I.x0.com is a domain controlled by two domain name servers at dns.ne.jp. Both are on different IP networks. Incoming mail for i.x0.com is handled by one mail server at x0.com. I.x0.com has one IP number (18.104.22.168), which also has a corresponding reverse pointer.
