However, there is one limitation to note: The whole thing usually only works with Fritz boxes that you have bought in free trade. Routers provided by the Internet provider are restricted in many places, so that they usually lack the appropriate setting options.
To set up alternative DNS servers, follow the steps described below for a Fritzbox 6591 Cable. However, the procedure should be applicable to all modern AVM routers.
First, open the Fritzbox user interface by typing the address in any browser fritz.box call. After you have logged in with your password, switch on the extended view. You can find the option by clicking on the three dots below each other in the top right.
Then navigate to via the left sidebar Internet / access data. In the following dialog, switch to the tab DNS server. Depending on whether you have only activated IPv4 or Dual Stack or Dual Stack Lite (DS Lite), you will find setting options for IPv4, IPv6 or both on this page.
Now click on the corresponding radio button, for example Use other DNSv4 servers. You can then use the two fields Preferred DNSv4 server and Alternative DNSv4 server enter the respective IP addresses. If necessary, proceed analogously with the addresses for IPv6 DNS servers.
Which public DNS server you use is largely a matter of taste. However, you should note that the DNS provider can see which websites you are visiting. After all, the domain names have to be resolved so that surfing behavior can be derived based on them – at least in part.
There are three major international providers of public DNS services that use the following IP addresses:
220.127.116.11 und 18.104.22.168 (IPv4)
2606:4700:4700::1111 und 2606:4700:4700::1001 (IPv6)
22.214.171.124 und 126.96.36.199 (IPv4)
2620:fe::fe und 2620:fe::9 (IPv6)
188.8.131.52 und 184.108.40.206 (IPv4)
2001:4860:4860::8888 und 2001:4860:4860::8844 (IPv6)
After you have entered the respective addresses, you just have to Take over click. You can see in the user interface whether the Fritzbox uses the new DNS servers Internet / online monitor / DNS server used. (ad)
