Verify if nameservers are responding to DNS requests using: $ dig [some-domain-name] @nameserver-1-in-resolv-conf If that works successfully, check contents of /etc/nsswitch.conf, esp. the hosts line. Following is the hosts line from my /etc/nsswitch.conf: hosts: files mdns_minimal [NOTFOUND=return] dns mdns If hosts line is okay, try stopping 'nscd' (if it is running) and then do: $ getent hosts [some-domain-name] If DNS resolution is not working, try resolving using some other nameservers, like 4.2.2.2, 208.67.222.222, 208.67.220.220 . If DNS resolution using other nameservers is also not working, try visiting http://72.14.207.99/ in web-browser if that works. Then you need to figure out which box is dropping UDP packets to port 53. You can also try adding '+tcp' to 'dig' arguments to see if name-resolution over TCP works or not.
