Configuring different DNS servers in the FRITZ!Box

DNS servers in the internet convert the alphanumeric names of internet servers to numeric IP addresses (for example avm.de in 212.42.244.80). For the name resolution of web addresses, the FRITZ!Box uses the DNS servers assigned to it by your internet service provider when it connects to the internet.

If you want to use different DNS servers in your home network, you can configure them in the FRITZ!Box user interface.

Requirements / Restrictions

  • You can only select 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.

      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 you can call up web pages even if the preferred DNSv4 server is unavailable.
  5. If you would like 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.
