Your router is the piece of network hardware that allows communication between your local home network—like your personal computers and tablets—and the internet.
Your router is configured to query DNS servers to find out where to locate websites on the world wide web. Inserting CloudVeil's DNS servers into your router (instead of the default) will result in basic web filtering of your entire network. Better yet, you can order a router and Wi-Fi kit from CloudVeil that's preconfigured, and more difficult to bypass.
