We pick m.root-servers.net, one of the 13 root servers (1), and ask it about my.hrw.com and learn that com is delegated to 13 name servers (2), so we ask l.gtld-servers.net where we learn that hrw.com is delegated to three name servers, including ns3.hmco.com (3), so we ask that one where we see a CNAME from my.hrw.com to hmhcocz.hs.llnwd.net, so we have to start all over again. We pick j.root-servers.net, one of the 13 root servers (4), and ask it about hmhcocz.hs.llnwd.net and learn that net is delegated to 13 name servers (5), so we ask c.gtld-servers.net where we learn that llnwd.net is delegated to four name servers, including dns12.llnwd.net (6), so we ask that one and get the following answer:
