Q. How do I set up my computer to use Comodo Secure DNS?
A. If you have a router, we recommend changing your setting there so that all the computers attached to that router will automatically be updated. However, if you would like to modify your computer instead, please follow the instructions for your particular operating system. Instructions can be found in the Switch Now section.
