Bonjour,
Bonjour,
I am wondering why some dns servers are available and some other are not
if I set them in resolv.conf (or other dns config files)?
The nameservers in resolv.conf will be tried.
And dig @80.67.169.12 sci-hub.se returns:
;; communications error to 80.67.169.12#53: host unreachable
;; communications error to 80.67.169.12#53: timed out
;; communications error to 80.67.169.12#53: timed out
Checking with telnet on ports 53 and 853 on ns0.fdn.fr. gives the
following reply:
> telnet ns0.fdn.fr. 853
Trying 80.67.169.12...
Connected to ns0.fdn.fr..
Escape character is '^]'.
Connection closed by foreign host.
That shows that there is some kind of server there and that it answers
on the standard dns ports. It just don't reply to any requests.
Perhaps misconfigured?
The dig utility you're using says that the (supposed) DNS server at that
address and port are not giving a valid DNS host response, neither does
it return a response within the timeout period.
By the way, the server at 80.67.169.40 (ns1.fdn.fr) is behaving the same
way.
