Ok, stole these notes from OpenDNS. But I want my own copy of these notes that I can find when I need it.

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 4.2.2.2,216.73.123.59;
# 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.

### Oh on the Prepend domain-name-servers. Please remember to change to your own DNS settings.
