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. An IPv6 address is represented as eight groups of four hexadecimal digits, each group representing 16 bits The groups are separated by colons (:). An example of an IPv6 address is: 2001:0db8:85a3:0000:0000:8a2e:0370:7334 The standards provide flexibility in the representation of IPv6 addresses.
