We pick e.root-servers.net, one of the 13 root servers (1), and ask it about mail.isi.edu and learn that edu is delegated to six name servers (2), so we ask a.edu-servers.net where we learn that isi.edu is delegated to four name servers, including ns.east.isi.edu (3), so we ask that one where we see a CNAME from mail.isi.edu to vapor.isi.edu, so we have to start all over again. We already know that ns.east.isi.edu is authoritative for isi.edu (4) and ask it about vapor.isi.edu and get the following answer:
