With a subnet mask of 255.255.255.240 (/28), each subnet has 14 available host addresses. A total of 16 subnets can be created with this subnet mask.

With a subnet mask of 255.255.255.240, it corresponds to a CIDR notation of /28. In this subnet, there are 4 bits available for host addresses (32 - 28 = 4), which means there are 2^4 = 16 possible host addresses in each subnet.

However, 2 addresses are reserved for network and broadcast addresses, leaving 14 usable host addresses in each subnet.

To calculate the number of subnets, you can use the formula 2^(number of subnet bits). In this case, there are 4 subnet bits (32 - 28 = 4), so you can create 2^4 = 16 subnets.

Therefore, each subnet has 14 usable host addresses, and you can create 16 subnets with the given subnet mask.

The complete question is:

Your organization has been assigned a block of IP addresses with the subnet mask 255.255.255.240. How many host addresses are available in each subnet, and how many subnets can be created with this subnet mask?
