blockerDNS is a DNS level ad blocker and fully customizable content filter that lets you take control of your internet and protect your privacy.


Note: For standard DNS, access is controlled by IP address. This is to prevent abuse of our servers by bad actors. When you sign in on the {{entity()}} website, your IP address is automatically whitelisted. Before changing your router's DNS settings, just make sure you sign in from a device on your WiFi first so that your house's IP is added to your account. You can always manually add/remove IPs in account management also.

Step 1
Sign into your Cisco router's admin page at or, depending on which router you have.

Step 2

Step 3
Choose the Lan Setup tab from the menu that's below the Setup option.

Step 5

Step 6
If you have a third field, you can just leave it blank.

Step 7
Click Save Settings.

Whichever computer(s) or device(s) you're using should be restarted so that it can reconnect to your router and get the new DNS information.
