We pick i.root-servers.net , one of the 13 root servers (1), and ask it about ds-any-fp2.wa1.b.yahoo.com and learn that com is delegated to 13 name servers (2), so we ask i.gtld-servers.net where we learn that yahoo.com is delegated to five name servers, including ns4.yahoo.com (3), so we ask that one and learn that wa1.b.yahoo.com is delegated to two name servers (4), so we ask yf2.yahoo.com and get the following answer:
