2. Choose the type of connection you have. For this example, in my case "Wireless", select the connexion (My case Auto unixmen) and click Edit

3- Inside editing " auto unixmen wireless" click on ‘IPv4 Settings’ tab.

4. Under ‘IPv4 Settings’, change the ‘Method’ to Automatic (DHCP) addresses only.

6. Put these nameserver addresses as your ‘DNS Servers’: 208.67.222.222, 208.67.220.220

7. Click ‘OK’ and reboot your machine. You can then visit http://welcome.opendns.com to confirm you are using OpenDNS. (Need registration)
8. NOTE:
To avoid having your settings get revoked after reboots, or after periods of inactivity you may need to make the following changes via the command line:
$ sudo cp /etc/resolv.conf /etc/resolv.conf.auto
$ gksudo gedit /etc/dhcp3/dhclient.conf
# append the following line to the document
prepend domain-name-servers 208.67.222.222,208.67.220.220;
# save and exit
$ sudo ifdown eth0 && sudo ifup eth0
You may be required to change eth0 to your own network device's name if it uses a non-standard name.

I guess they wanted to make something diferent, but did not go as good as they thought it would, comparing with other ubuntu releases.
