IPv6 – 6 to 4 Tunneling
6to4 tunnelling allows v6 packets to travel across v4 clouds by using 6to4 gateway routers to configure a special address and prefix. The address prefix 2002: is reserved for 6to4 based addresses. Added to this address is the v4 address which is 32 bits making an end prefix of /48, the next 16 bits are used for v6 subnets which allows 65,536 subnets
