Hello everyone,

  My institute (www.asiaa.sinica.edu.tw) uses openDNS as dns server's forwarder,

 

208.67.222.123; 208.67.220.123;

 

we are 140.109.177.x/24 and when we browse this url

http://www.aanda.org

it doesn't work (the browser keeps waiting forever and webpage never shown)

 

but when our DNS gave up OpenDNS forwarders(if our dns do the lookup by itself, not relying on opendns)

then this http://www.aanda.org works

here I list the linux dig command for with opendns (notworking) and without opendns (working)

 

 

 

with opendns (it doesn't work)

$dig www.aanda.org

  Both command outputs are with 140.109.177.3 (dns.asiaa.sinica.edu.tw) as DNS service, not with OpenDNS.  So I cannot see a difference between OpenDNS and 140.109.177.3.  You may try again with using OpenDNS.

  dig www.aanda.org. @208.67.220.123

  Btw, for me the DNS query returns the same with OpenDNS as with your 140.109.177.3.  Your problem is apparently of a different nature, not with www.aanda.org.  Visit http://welcome.opendns.com/ to see if you're using OpenDNS at all.
