Blocking Public DNS: Fritz!box Router
Login to your router.
Click “Network” in the “Home Network” menu, then select the “Network Settings” tab.
Scroll down and select “IPv4 Routes” Click the “New IPv4 Route” button.
Add the following to the Route list:.
- Network/Host IP = 184.108.40.206
- Netmask = 255.255.255.252
- Gateway = your router IP or add 1 to the last number of your router IP. So if your router IP is 192.168.1.1 the last number of your router IP is 1 (1 + 1 = 2 ) so your getaway IP will be 192.168.1.2
- Enable the option “IPv4 route active”.
