I'm having a problem trying to look up a certain DNS name on the internet. For some reason I keep facing a SERVFAIL thought the correct result is displayed - like the DNS name is being resolved twice (external/local?).
I have no trouble looking up anything else, but this single DNS name gives me a headache. Other servers within my farm do lookups fine on this domain.
Let me give you some informations.
OS: Ubuntu 14 (with bind9 installed)
nameserver 22.214.171.124 # opendns nameserver 127.0.0.1
The faulty lookup:
# host whois.verisign-grs.com whois.verisign-grs.com has address 126.96.36.199 whois.verisign-grs.com has IPv6 address 2001:503:5419:1000::74 Host whois.verisign-grs.com not found: 2(SERVFAIL)
If i did not have the opendns entry in my resolv.conf, the error would either be a timeout (usually the first answer) or the SERVFAIL.
Could the local lookup tools be broken, or could it happen that my DNS lookups are blocked on some level?
