 ===== IPv6 Service Type =====
-IPv6 has a number of services, or modes of operation which it can use. Some partly depend on IPv4 services, and others are run entirely independent of IPv4. Please ask your Internet Provider or search the Web to learn which IPv6 service type is used on your your ISP's network.

 This is the Default state. IPv6 is disabled by default. (IPv6 traffic will still flow/work if in access point mode, for example.)

 ==== DHCPv6 with Prefix Delegation ====
-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. Check your configuration in the Basic/[[:network|Network]] menu to learn more.

-**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).
