DNS delegation of edxwww.facbook.com updated:


We pick j.root-servers.net, one of the 13 root servers (1), and ask it about edxwww.facbook.com and learn that com is delegated to 13 name servers (2), so we ask j.gtld-servers.net where we learn that facbook.com is delegated to two name servers, including b.ns.facebook.com (3), so we ask that one where we see a CNAME from edxwww.facbook.com to www.facebook.com, so we have to start all over again. We already know that d.gtld-servers.net is authoritative for com (4) and ask it about www.facebook.com and learn that facebook.com is delegated to two name servers (5), so we ask a.ns.facebook.com and see a second CNAME from www.facebook.com to star-mini.c10r.facebook.com. We start over for the third time and we already know that a.ns.facebook.com is authoritative for facebook.com (6) and ask it about star-mini.c10r.facebook.com and learn that c10r.facebook.com is delegated to two name servers (7), so we ask a.ns.c10r.facebook.com and get the following answer:
