We pick f.root-servers.net , one of the 13 root servers (1), and ask it about alt21.aspmx.l.google.com and learn that com is delegated to 13 name servers (2), so we ask b.gtld-servers.net where we learn that google.com is delegated to four name servers, including ns3.google.com (3), so we ask that one and get the following answer:
