We pick i.root-servers.net, one of the 13 root servers (1), and ask it about www.postinitraining.com and learn that com is delegated to 13 name servers (2), so we ask g.gtld-servers.net where we learn that postinitraining.com is delegated to four name servers, including ns4.google.com (3), so we ask that one where we see a CNAME from www.postinitraining.com to www3.l.google.com, so we have to start all over again. We already know that k.gtld-servers.net is authoritative for com (4) and ask it about www3.l.google.com and learn that google.com is delegated to four name servers (5), so we ask ns3.google.com and get the following answer:
