In most Unix operating systems, your DNS settings are configured in /etc/resolv.conf. To use Internet Guide:

1. Open /etc/resolv.conf in any text editor.
2. Comment out any nameserver or search lines with #.
3. Add the following two lines:
   nameserver 188.40.157.19
nameserver  156.154.71.22
4. Save the file and exit the editor.
5. Test your new settings →

To disable: Simply remove our TidyDNS nameserver lines from resolv.conf and uncomment the previous settings.

Many popular distributions use dhclient if your interface is set to DHCP. To use TidyDNS with dhclient:

1. Open dhclient.conf, typically located at /etc/dhcp3/dhclient.conf, in any text editor.
2. Uncomment or add the following line:
   prepend domain-name-servers 188.40.157.19,154.156.71.22;
3. Restart your network interface. If you are using NetworkManager, you can do this by clicking on the icon and selecting your interface to activate the changes.

To disable: Comment out or remove the line above.

In most cases, DHCP-enabled devices in your network will retrieve DNS settings automatically from your router; by configuring your router to use TidyDNS, these devices will use TidyDNS as well.

The exact method of configuring static DNS settings varies widely from router to router, but usually appears under the DHCP configuration section. For example, under Basic Setup - Network Address Server Settings (DHCP) in the Linksys WRT54G, there are three entries for Static DNS. Entering the first DNS server as, 188.40.157.19 and the second DNS server as 156.154.71.22, will cause the router and all DHCP devices in your network to query TidyDNS for their DNS needs
