Example: WebFeb 2, 2024 · A 6to4 IPv6 address always starts with 2002 and then is followed by the IPv4 address, split into two 16-bit parts, written in hexadecimal, making for a 48-bit long prefix. For example, the 6to4 prefix for the IPv4 address 192.0.2.4 is 2002:c000:0204::/48. There is then room for an IPv6 16-bit subnet field and 64 bits for hosts.
