Configuring different DNS servers in the FRITZ!Box

DNS servers in the internet translate the names of internet servers to numeric IP addresses (for example avm.de to 212.42.244.122). By default, the FRITZ!Box uses the internet service provider's DNS server for name resolution. You can also configure other, free DNS servers in the FRITZ!Box (for example Digitalcourage, Digitale Gesellschaft Schweiz, Quad9).

Requirements / Restrictions

  • You can only configure a different DNSv6 server if IPv6 support is enabled in the FRITZ!Box (under "Internet > Account Information > IPv6").
  • The FRITZ!Box always uses your internet service provider's DNS servers for internet telephony, push service mails, and several other functions.

Note:All instructions on configuration and settings given in this guide refer to the latest FRITZ!OS for the FRITZ!Box.

Configuring a DNS server

  1. Click "Internet" in the FRITZ!Box user interface.
  2. Click "Account Information" in the "Internet" menu.
  3. Click on the "DNS Server" tab. If the tab is not displayed, enable the Advanced View first.
  4. If you want to configure other DNSv4 servers:
    1. Enable the option "Use other DNSv4 servers".
    2. Enter the IP address of the DNSv4 server in the "Preferred DNSv4 server" field.

      ATTENTION!If the IP address of the DNS server is entered incorrectly, you will not be able to access the internet over IPv4.

    3. Enter the IP address of a second DNSv4 server in the "Alternative DNSv4 server" field so that websites can be opened even if the preferred DNSv4 server is unavailable.
  5. If you want to configure other DNSv6 servers:
    1. Enable the option "Use other DNSv6 servers".
    2. Enter the IP address of the DNSv6 server in the "Preferred DNSv6 server" field.

      ATTENTION!If the IP address of the DNS server is entered incorrectly, you will not be able to access the internet over IPv6.

    3. Enter the IP address of a second DNSv6 server in the "Alternative DNSv6 server" field so that websites can be opened even if the preferred DNSv6 server is unavailable.
  6. Click "Apply" to save the settings and on the FRITZ!Box, confirm that the procedure may be executed if asked to do so.
