If you would like to change that to your router or your ISP or some other provider, you can issue this command, provided you have two IP addresses of the providers:
{{Code|hda-change-dns FIRST_DNS_IP SECOND_DNS_IP}}
For instance, if you would like to use [http://code.google.com/speed/public-dns/ Google's Public DNS] service, you would do:
{{Code|hda-change-dns 8.8.8.8 8.8.4.4}}
To revert back to the default OpenDNS settings use:
{{Code|hda-change-dns 208.67.222.222 208.67.220.220}}
