the method to convert IPv4 ranges to IPv6
IPv4 to IPv6 is trivial.
:: detour to investigate issue, with pause for hilarity thanks to highly-google-ranked site having blatant text-encoding problems ::
Quoting randomly from https://isc.sans.edu/tools/ipv6.html *
IPv4: a.b.c.d translates to IPv6 2002:ab:cd::ab:cd
where :: = :0: = :0000: (this is part of the IPv6 definition)
and a, b, c, d are each converted from decimal to hexadecimal (255 > ff and so on down).
There are probably dozens of online converters, or you can make your own in, at most, five minutes of programming.
Outside of that 2002:a:b:0:a:b range, you can't go in the other direction because there doesn't seem to be anywhere to go to.
By my count, all of IPv4 = 1/2^96 of IPv6. Brrr.
* The ".edu" is more than a little borderline, but that's IANA's call, not mine. Or possibly ARIN. I forget.
