> Yes, you mentioned earlier that you were running dnsmasq - that means you are running a local DNS service. Have you configured that with the address(es) of at least one external DNS resolver. As I read the description on Wikipedia, dnsmasq is a forwarder not a resolver - that means that it can't do the recursive lookups a resolver does, just forward queries to an outside resolver and cache the responses.

As local DNS service in this situation means dnsmasq i do see not much
added value. Besides i am running my own dns server in my network.
