We pick a.root-servers.net, one of the 13 root servers (1), and ask it about iran-computer-security.googlegroups.com and learn that com is delegated to 13 name servers (2), so we ask f.gtld-servers.net where we learn that googlegroups.com is delegated to four name servers, including ns2.google.com (3), so we ask that one where we see a CNAME from iran-computer-security.googlegroups.com to googlegroups.l.googleusercontent.com, so we have to start all over again. We already know that a.gtld-servers.net is authoritative for com (4) and ask it about googlegroups.l.googleusercontent.com and learn that googleusercontent.com is delegated to four name servers (5), so we ask ns1.google.com and get the following answer:
