We pick f.root-servers.net, one of the 13 root servers (1), and ask it about nokiamail.com and learn that com is delegated to 13 name servers (2), so we ask f.gtld-servers.net where we learn that nokiamail.com is delegated to six name servers, including ns2.nokia.com (3), so we ask that one and get the following answer:
Nokiamail.com is a domain controlled by six domain name servers at nokia.com. Some of them are on the same IP network. Incoming mail for nokiamail.com is handled by three mail servers at yahoodns.net having a total of 16 IP numbers. There are 32 duplicated IP numbers. Some of them are on the same IP network. Nokiamail.com has one IP number (66.54.66.192), but the reverse is static-66-192.atl.nokia.net.
