WebIPv6 block size is based on the number and size of subnets to be assigned to customers, not on the number of IP addresses required by customers. ISPs will typically assign one subnet (/48 or smaller) to each customer. The default /32 minimum allocation is sufficient for many ISPs since it contains 65,536 /48 subnets to assign to customers. http://www.steves-internet-guide.com/ipv6-guide/

Web13 sep. 2024 · As stated in [ RFC3513 ], IANA should limit its allocation of IPv6-unicast address space to the range of addresses that start with binary value 001. The rest of the global unicast address space (approximately 85% of the IPv6 address space) is reserved for future definition and use, and is not to be assigned by IANA at this time. On the Internet, data is transmitted in the form of network packets. IPv6 specifies a new packet format, designed to minimize packet header processing by routers. Because the headers of IPv4 packets and IPv6 packets are significantly different, the two protocols are not interoperable.
