Each successive CIDR prefix should be twice its next-lowest ordinal; but you are off by one. (a /74 contains 18014398509481984, not 18014398509481985 addresses.) Every shorter prefix after that is incorrect. You’ve got an error in your table at the /74 level. Each successive CIDR prefix should be twice its next-lowest ordinal; but you are off by one.

I was trying to gain a better understanding of IPv6 in General, and this put it all into perspective for me. Again Thank you.

But is there any mathematical way to calculate the number of IP addresses? I thought it was 2 ^ (128 CIDR), but that only works for the highest CIDR subnet. Like: for /48 that should give you 1208925819614629174706176 not 1,208,925,819,614,629,500,000,000 useful table!

I just see that he.net is recommending a /48 for residential users. Still trying to figure out why a /64 isn't enough. thanks for the table!
