We pick c.root-servers.net, one of the 13 root servers (1), and ask it about gedas.us and learn that us is delegated to six name servers (2), so we ask f.cctld.us where we learn that gedas.us is delegated to five name servers, including ns2-auth.sprintlink.net (3), so we ask that one and get the following answer:
Gedas.us is a domain controlled by five domain name servers at vw.com and sprintlink.net having a total of eight IP numbers. Some of them are on the same IP network. Incoming mail for gedas.us is handled by two mail servers at vw.com. Both are on the same IP network. Gedas.us has one IP number (139.1.1.5).
