We pick c.root-servers.net, one of the 13 root servers (1), and ask it about auth4.dns.cogentco.com and learn that com is delegated to 13 name servers (2), so we ask l.gtld-servers.net where we learn that cogentco.com is delegated to four name servers, including auth4.dns.cogentco.com (3), so we ask that one and get the following answer:
