DNS delegation of webmail.cfl.rr.com updated:


We pick k.root-servers.net, one of the 13 root servers (1), and ask it about webmail.cfl.rr.com and learn that com is delegated to 13 name servers (2), so we ask d.gtld-servers.net where we learn that rr.com is delegated to five name servers, including dns2.rr.com (3), so we ask that one and learn that cfl.rr.com is delegated to two name servers (4), so we ask uns1.bhn.net where we see a CNAME from webmail.cfl.rr.com to cdptpa-cfl-vip.email.rr.com, so we have to start all over again. We already know that dns3.rr.com is authoritative for rr.com (5) and ask it about cdptpa-cfl-vip.email.rr.com and get the following answer:
