CCNA-1.12: Identify the appropriate IPv6 addressing scheme to satisfy addressing requirements in a LAN/WAN environment


IPv6 addressing is designed differently than IPv4.  Subnetting is used in IPv4 to more efficiently use the small number of available addresses. IPv6 has a large enough address space without subnetting to accommodate devices for the foreseeable future.  The local area subnet always uses 64 bits for the routing prefix and 64 bits for the host, which is known as the interface identifier. 2000::/3 is the IPv6 Global Unicast range based on RFC4291
