We pick m.root-servers.net, one of the 13 root servers (1), and ask it about yahoo-emocion.com and learn that com is delegated to 13 name servers (2), so we ask g.gtld-servers.net where we learn that yahoo-emocion.com is delegated to five name servers, including ns2.yahoo.com (3), so we ask that one and get the following answer:
