We pick a.root-servers.net, one of the 13 root servers (1), and ask it about webmail.masterskill.edu.my and learn that my is delegated to seven name servers (2), so we ask ns30.cdns.net where we learn that masterskill.edu.my is delegated to six name servers, including ns4.dnsexit.com (3), so we ask that one where we see a CNAME from webmail.masterskill.edu.my to ghs.google.com, so we have to start all over again. We pick i.root-servers.net, one of the 13 root servers (4), and ask it about ghs.google.com and learn that com is delegated to 13 name servers (5), so we ask g.gtld-servers.net where we learn that google.com is delegated to four name servers, including ns2.google.com (6), so we ask that one and see a second CNAME from ghs.google.com to ghs.l.google.com. We start over for the third time and we already know that ns4.google.com is authoritative for google.com (7) and ask it about ghs.l.google.com and get the following answer:
