6t04 is an Internet transition mechanism for migrating from Internet Protocol version 4 (IPv4) to version 6 (IPv6), a system that allows IPv6packets to be transmitted over an IPv4 network (generally the IPv4Jnternet) without the need to configure explicit tunnels.

6t04 performs three functions:

-Asslqns a block of IPv6 address space to any host or network that has a global IPv4 address.-Encapsulates IPv6 packets inside IPv4 packets for transmission over an IPv4 network using6in4.-Routes traffic between 6t04 and "native" IPv6 networks.Address block allocation

IPv4:

IPv6:For any 32-bit global IPv4 address that is assigned to a host, a 48-bit 6t04 IPv6 prefix can be constructed for use by that host (and if applicable thenetwork behind it) by appending the IPv4 address to 2002::116.

For example, the global IPv4 address 192.0.2.4 has the corresponding 6t04 prefix 2002:cOOO:0204::/48. This gives a prefix length of 48 bits, whichleaves room for a 16·bit subnet field and 64 bit host addresses within the subnets.

Any IPv6 address that begins with the 2002::116prefix (in other words, any address with the first two octets of 2002 hexadecimal) is known asa 6t04 address, as opposed to a native IPv6 address which does not systematically use transition technologies.
