We pick e.root-servers.net, one of the 13 root servers (1), and ask it about ns.psi.net and learn that net is delegated to 13 name servers (2), so we ask c.gtld-servers.net where we learn that psi.net is delegated to two name servers, including auth1.dns.cogentco.com (3), so we ask that one and get the following answer:
