> The IPv4 32-bit address space should have been included in the IPv6 address space, instead of having 2 separate address spaces. Like > Addresses in this group consist of an 80-bit prefix of zeros, the next 16 bits are ones, and the remaining, least-significant 32 bits contain the IPv4 address. For example, ::ffff:192.0.2.128 represents the IPv4 address 192.0.2.128. A previous format, called "IPv4-compatible IPv6 address", was ::192.0.2.128; however, this method is deprecated.[5] * https://en.wikipedia.org/wiki/IPv6#IPv4-mapped_IPv6_addresses https://en.wikipedia.org/wiki/IPv6#IPv4-mapped_IPv6_addresse... ?

Also: > For any 32-bit global IPv4 address that is assigned to a host, a 48-bit 6to4 IPv6 prefix can be constructed for use by that host (and if applicable the network behind it) by appending the IPv4 address to 2002::/16. > For example, the global IPv4 address 192.0.2.4 has the corresponding 6to4 prefix 2002:c000:0204::/48. This gives a prefix length of 48 bits, which leaves room for a 16-bit subnet field and 64 bit host addresses within the subnets. * https://en.wikipedia.org/wiki/6to4 https://en.wikipedia.org/wiki/6to4
