Ubuntu 11.04

If I try to resolve a host name to IP of domains that don't exist, my box always resolves to

root@system:~# ping
PING ( 56(84) bytes of data.

root@system:~# cat /etc/resolv.conf

root@system:~# cat /etc/hosts localhost

# The following lines are desirable for IPv6 capable hosts
::1 localhost ip6-localhost ip6-loopback
fe00::0 ip6-localnet
ff00::0 ip6-mcastprefix
ff02::1 ip6-allnodes
ff02::2 ip6-allrouters

Seems like a hijack of my DNS resolution. Not sure what to check for this. Any suggestions? Thanks.

it could be possible that DNS queries are redirected ...

the Ubuntu machine is probably connected to a Router , I would check this Router and see what entries it has for DNS
Resolution and if it has iptables port forwarding for port 53 TCP and UDP .
