On my dedicated server at server4you.de I had theese nameservers preconfigured:
nameserver 184.108.40.206 nameserver 220.127.116.11
they were unable to resolve my domain names 2xfun.de and 2x.to
i ran some dns check like here http://www.intodns.com/2xfun.de and everything looked fine.
after changing the nameserers to googles 18.104.22.168 and 22.214.171.124 everything resolved perfectly.
Is there anything wrong with my zones?
