one for broadcast i.e 256
and anthoer one is network i.e 0(zero)
It does not require a subnet mask.
Use the formula 2n - 2 to find the number of clients available in a subnet. The 'n' refers to the number of bits available for client addresses, and thus will vary depending on the starting network type (class A, B, or C). If you are using the 0th subnet (as in Cisco routers) then the formula is 2n
Subnet mask for the above is 255.0.0.0
In a Class A address, the default subnet mask is 255.0.0.0, allowing for a large number of hosts within a single network, but with 16 bits designated for the subnet ID, the subnet mask becomes 255.255.0.0. In contrast, a Class B address has a default subnet mask of 255.255.0.0, and with 8 bits for the subnet ID, the subnet mask would typically be 255.255.255.0. Thus, the key difference lies in the number of bits allocated for the subnet ID and the resulting subnet masks, affecting the number of available subnets and hosts per subnet.
By changing subnet mask..from 255.255.224.0 to 255.255.240.0 Number of subnetworks increase and the number of host in each subnetwork decreases
To calculate a subnet mask, first determine the number of subnets needed and the number of hosts per subnet. Use the formula (2^n \geq \text{number of subnets}) for subnetting and (2^h - 2 \geq \text{number of hosts}) for host calculation, where (n) is the number of bits borrowed for subnets and (h) is the number of bits left for hosts. For example, if you start with a Class C address like 192.168.1.0 and want 4 subnets, you would borrow 2 bits (since (2^2 = 4)), resulting in a subnet mask of 255.255.255.192 (or /26), which allows for 62 hosts per subnet.
192.168.14.100
There is no technical term called "subnet mass number." It might be a misconstrued term. Subnetting is dividing a network into smaller subnetworks for better organization and security. Mass number is used in chemistry to denote the total number of protons and neutrons in an atom's nucleus.
A subnet mask for a /512 subnet is not valid because subnet masks are defined in powers of two, and the maximum number of hosts in a subnet is limited by the number of bits in the IP address (32 bits for IPv4). The largest valid subnet mask is /32, which allows for a single IP address. However, if you meant a subnet that allows for 512 hosts, the correct subnet mask would be /23, which provides 512 addresses (510 usable for hosts).

because that is the last number of the subnet. the last number in a subnet is used as the broadcast domain. the first number is also not usable. an example would be: id 192.168.20.XX subnet 0f 255.255.255.128 192.168.20.0 and 192.168.20.127 may not be used and 192.168.20.128 starts the next subnet making 192.168.20.128 and 192.168.20.255 not usable
32 host per 8 subnet.
