 [6to4 Anycast Relay]
-to4 is a transitional protocol for migrating from IPv4 to IPv6.  6to4 acts as a transparent transport layer between IPv6 nodes. It allows IPv6 packets to be transmitted over an IPv4 network, such as the Internet, without requiring you to configure explicit tunnels. 6to4 hosts and networks communicate with native IPv6 networks via Special relay servers, known as "6to4 Anycast Relays".

-**Prefix Length**  \\ The network prefix is analogous to an IPv4 subnet mask. It represents the network portion (most significant bits) of the address. These leading bits are identical on all hosts on your assigned network.
+The IAID is normally chosen by the requesting (FreshTomato) router. (DUID + IAID) ==> unique assignment (both pieces of data/values from client side) for the server. (Default ID: 0).
-Other options commonly used iinclude 56 bits. (Default: 64).
+The DUID tells the DHCP server //who// is making the request (the device/router).
