How to Block Public DNS on TP-LINK Routers

HOW TO SETUP BLOCKS

LOGIN TO YOUR ROUTER

  1. Open your a blank webpage and into the web address bar type http://192.168.1.1 (also try http://192.168.0.1 or http://192.168.2.1)
  2. Enter router username and password. The default username & password is usually admin for both.

ADD STATIC ROUTES

  1. Make sure you take note of your ‘IP ADDRESS’ and then select ‘Advanced Routing’
  2. Select the button ‘Add New’
  3. Add the following to the RouteList:
  • Network/Host IP: 8.8.8.8
  • Netmask: 255.255.255.255
  • Gateway: your router IP
  1. Click the button ‘Save’
  2. Repeat number three and four under ADD STATIC ROUTES
  • Network/Host IP: 8.8.4.4
  • Netmask: 255.255.255.255
  • Gateway: your router IP
  • Network/Host IP: 208.67.222.222
  • Netmask: 255.255.255.255
  • Gateway: your router IP
  • Network/Host IP: 209.244.0.3
  • Netmask: 255.255.255.255
  • Gateway: your router IP

PING TEST

  1. Open the Command Prompt or Terminal
  • For Windows: Press the Windows Key AND the R Key at the same time on your keyboard. Type in cmd and press Enter.
  • For Mac OSX: In the upper right corner of your screen, where the search function is, type in ‘Terminal’and open the program.
  1. Run the following commands
  • Type in:ping 8.8.8.8
  • Type in:ping 208.67.222.222
  • Type in:ping 209.244.0.3

Note: The ping tests above should not succeed. If any of them provide you with a result, examine your static routes or restart the wireless router and try this step again until the ping don’t succeed. You might also need to use a different gateway IP such as 127.0.0.1 or 192.168.0.253. Basically any inaccessible IP that the wireless router allows should function.

Reboot Device

            Turn off your device and unplug the power cable from the router. Wait for 30 seconds. Plug in router and turn on device
