Done! You should now be able to visit the Main OpenNIC Project Site. In addition to other OpenNIC Sponsored Top Level Domains you also have access to all alt-root Peer Top Level Domain as well.

NOTE: If after a certain time o after every reboot, the DNS keeps getting lost, follow these instructions:

• Go to Applications->Accessories->Terminal and type:

sudo gedit /etc/dhcp3/dhclient.conf

Type the sudo password. The file dhclient.conf will open.

• Go to the end of the file and add the following line to the END of the file:

prepend domain-name-servers DNS1, DNS2, DNS3;

Replace DNS1, DNS2 and DNS3 with the three nearest OpenNIC DNS to you.

• Save and close the file.

That's all. You may need to restart.
