We pick g.root-servers.net , one of the 13 root servers (1), and ask it about z1-ibo-dns.am.lilly.com and learn that com is delegated to 13 name servers (2), so we ask i.gtld-servers.net where we learn that lilly.com is delegated to four name servers, including dns1i.xh1.lilly.com (3), so we ask that one and learn that am.lilly.com is delegated to one name server (4), so we ask dns1c.d51.lilly.com and get the following answer:
