We pick h.root-servers.net , one of the 13 root servers (1), and ask it about ds-fp2.wg1.b.yahoo.com and learn that com is delegated to 13 name servers (2), so we ask e.gtld-servers.net where we learn that yahoo.com is delegated to five name servers, including ns1.yahoo.com (3), so we ask that one and learn that wg1.b.yahoo.com is delegated to eight name servers (4), so we ask yf4.yahoo.com where we see a CNAME from ds-fp2.wg1.b.yahoo.com to ds-any-fp2.wa1.b.yahoo.com , so we have to start all over again. We already know that ns4.yahoo.com is authoritative for yahoo.com (5) and ask it about ds-any-fp2.wa1.b.yahoo.com and learn that wa1.b.yahoo.com is delegated to two name servers (6), so we ask yf2.yahoo.com and get the following answer:
