... For any 32-bit global IPv4 address, a 48-bit 6to4 IPv6 prefix can be constructed for use by that host (and if applicable the network behind it) by prepending 2002 (hex) to the IPv4 address. For example, for192.0.2.42, the corresponding 6to4 prefix would be 2002:c000:022a::/48. This gives a prefix le ...
