We pick a.root-servers.net, one of the 13 root servers (1), and ask it about h.fo and learn that fo is delegated to four name servers (2), so we ask pch.nic.fo where we learn that h.fo is delegated to two name servers, including pdns01.domaincontrol.com (3), so we ask that one and get the following answer:
H.fo is a domain controlled by two domain name servers at domaincontrol.com having a total of four IP numbers. All four of them are on different IP networks. Incoming mail for h.fo is handled by one mail server at hotmail.com having a total of two IP numbers. Both are on the same IP network. H.fo has one IP number (199.59.241.250), but the reverse is ?.
