We pick c.root-servers.net, one of the 13 root servers (1), and ask it about hr-hr.facebook.com and learn that com is delegated to 13 name servers (2), so we ask k.gtld-servers.net where we learn that facebook.com is delegated to two name servers, including a.ns.facebook.com (3), so we ask that one where we see a CNAME from hr-hr.facebook.com to star.facebook.com, so we have to start all over again. We already know that b.ns.facebook.com is authoritative for facebook.com (4) and ask it about star.facebook.com and see a second CNAME from star.facebook.com to star.c10r.facebook.com. We start over for the third time and we already know that b.ns.facebook.com is authoritative for facebook.com (5) and ask it about star.c10r.facebook.com and learn that c10r.facebook.com is delegated to two name servers (6), so we ask b.ns.c10r.facebook.com and get the following answer:
