Remember, the IPv6 address space can be huge. Total IP Addresses: The total IP addresses in a subnet refer to the sum of usable IP addresses, network address, and broadcast address. This IPv6 subnetting calculator is provided to help you understand the IPv6 address space better and to study for exams you should always use /64 subnet masks on real networks. A subnetting cheat sheet allows administrators to quickly reference subnet sizes so they can find the IP space and subnet size required for a specific need.
