CIDR Notation Explanation
/8 This subnet mask allows for 24 bits for host addresses within the IP address range 0.0.0.0 to 255.255.255.255, providing a total of 16,777,216 possible host addresses.
/16 With a subnet mask allowing 16 bits for host addresses, it covers the IP address range 0.0.0.0 to 0.255.255.255, offering 65,536 possible host addresses.
/24 This subnet mask provides 8 bits for host addresses, covering the IP address range 0.0.0.0 to 0.0.0.255, with 256 possible host addresses.
/32 This represents a point-to-point link or a single host, as it includes only one IP address (0.0.0.0).

CIDR Notation Explanation
/48 Provides a vast number of possible subnets and is typically used for very large organizations or service providers.
/56 Used for smaller organizations or larger branches within a larger network.
/64 The standard subnet size for local area networks (LANs) and is commonly used for end-user assignments.
/96 Often used for point-to-point links between routers.
/112 Used for very small subnets within larger networks or for specialized purposes.
/120 Used for very small subnets or point-to-point links within a larger network.
/128 Represents a single IPv6 address, typically used for loopback or specific device assignments.
