Once you have completed your OpenDns set up you can add the below sites to your network settings under Manage individual domains/Always block. This should block most ads on every device connected to your home modem/router.
If you used a Netgear router where OpenDns is built in you’re done.
If you used your own router don’t forget to request a static ip address from your ISP as stated in Step 2. This will ensure your OpenDns settings stay in place.
