6ghs.l.google.com.google.com.(ns4,ns3,ns2,ns1).google.com.
We pick m.root-servers.net, one of the 13 root servers (1), and ask it about mail.duocphamaau.com and learn that com is delegated to 13 name servers (2), so we ask d.gtld-servers.net where we learn that duocphamaau.com is delegated to four name servers, including ns4.zonedns.vn (3), so we ask that one where we see a CNAME from mail.duocphamaau.com to ghs.google.com, so we have to start all over again. We already know that g.gtld-servers.net is authoritative for com (4) and ask it about ghs.google.com and learn that google.com is delegated to four name servers (5), so we ask ns2.google.com 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 (6) and ask it about ghs.l.google.com and get the following answer:
