A /64 in IPv6 is 2^64 IP addresses (it is 128 bit). 256 IPv6 addresses is /120. The simple reason why they do not give smaller blocks is the VPS company themselves are assigned a minimum of /64 for network purposes. That means they have 4 billion blocks of 4 billion IPs so why be stingy :)

- eknkc 12y agoIf they give everyone their own /64 subnet, it would still be like there were 4 billion of entire ipv4 address spaces available. Given that the planet can run on a single ipv4 space right now, that's an awful lot to run through.

- marcosdumay 12y agoThey'll be sorry because they'll have to ask another block from ICANN? They don't look THAT hard to deal with. They have an entire IPv4 space of IPv4 spaces to distribute, but that's still a ridiculously low amount near the total number of IPv6 addresses.
