Why don't DNS root servers answer?
- by JustTrying
If I try to query a root server with dig, I never receive an answer.
For example the output for dig @b.root-servers.net www.ubuntu.com is
; << DiG 9.8.1-P1 << @b.root-servers.net www.ubuntu.com
; (1 server found)
;; global options: +cmd
;; connection timed out; no servers could be reached
But if I query other servers (the one of my ISP, or 8.8.8.8), they answer correctly.
Why?
