-This configuration method is one of the most commonly used. It provides native IPv6 connectivity for your network. It allows the ability to assign different IPv6 address ranges for bridge 0 (br0) to 3 (br3) if you're given a prefix with length smaller than 64 (for example 60 or 56) from your Internet provider. The option to assign IPv6 address ranges for bridge 1 (br1) to 3 (br3) is only visible if the bridges already exist.

-**Configuration example for German Telekom ISP**+ \\
  
-Europe's biggest telecommunications company supports a dual-stack setup (IPv4 & IPv6). By default, German Telekom provides a prefix length of 56 for regular consumers. A prefix length of 64 (the default configuration for FreshTomato) will also work, but eliminates the possibility of assigning different IPv6 address ranges for bridge 1 (br1) to 3 (br3).+Example Configuration: German Telekom

A prefix length of 64 (FreshTomato's default) will also work. However, that eliminates the possibility of assigning different IPv6 address ranges for bridge 1 (br1) to 3 (br3).

 +===== IPv6 DUID Type =====
 +
 +Every DHCP client and server have a DHCP Unique Identifier, or "DUID". The DHCP server uses the DUID to identify clients for the selection of configuration parameters.
 +
 +Options:
 +
 +  * DUID-LL (default)
 +  * DUID-LLT
 +
 + \\
 +
 +DUID-LL will use the LAN (eth0) MAC address and will not change (remain static) over time. DUID-LLT will, in addition, include time value, and will change on every reboot or reconnect of the WAN interface. You can see the currently used DUID on the Status Overview menu.
 +
 +Support for this option started with release 2022.4.
 +
 +Note: DUID-EN, DUID-UUID or custom DUIDs are currently not supported.
