We pick h.root-servers.net, one of the 13 root servers (1), and ask it about dns.rcn.net and learn that net is delegated to 13 name servers (2), so we ask f.gtld-servers.net where we learn that rcn.net is delegated to four name servers, including auth1.dns.rcn.net (3), so we ask that one and get the following answer:
Dns.rcn.net is a domain controlled by four domain name servers at rcn.net having a total of five IP numbers. Some of them are on the same IP network. Incoming mail for dns.rcn.net is handled by one mail server also at rcn.net.
