Prior to the introduction of CIDR, IPv4 network ,prefixes, could be directly obtained from the IP address based on the class (A, B, or C, which vary based on the range of IP addresses they include) of the address and the network mask.

Global Unicast Addresses prefixes: The prefix is the part of the IPv6 address that indicates the network. Prefixes for IPv6 routes and subnet identifiers are similar to Classless Inter-Domain Routing (CIDR) notation for IPv4. For the IPv4 network 172.16.0.0 255.255.0.0, we can consider 172.16/16 as the prefix.

ISP(config)#ipv6 unicast-routing. The global prefix is configured with the ipv6 local pool command: ISP(config)#ipv6 local pool GLOBAL_POOL 2001:DB8:1100::/40 48. This tells the router that we have a pool called GLOBAL_POOL and that we can use the entire 2001:DB8:1100::/40 prefix. Each DHCP client, however, will receive a /48 prefix out of this pool.
