IP addresses are typically in the same format as a 32-bit number, shown as four decimal numbers each with a range of 0 to 255, separated by dots—each set of three numbers is called an octet. This format is used by IP version 4 (or IPv4). With it, you could—in theory—have 0.0. 0.0 to 255.255.

256 /64 subnets
Medium customers get a /56 prefix. That gives them 256 /64 subnets. Small customers (meaning home or small office customers) get a single /64 prefix.
What IPv6 address should I use?
The 126-bit prefix is typically used for point-to-point links similar to the IPv4 address-conservative /30 allocation for point-to-point links. However, the address space in IPv6 is significantly larger than the IPv4 address space. The general recommendation is to use /64 on point-to-point links.
