How many host addresses are available on the network 192.168.1.0 subnet 255.255.255 240?
To determine the number of host addresses available on a subnet, we need to know the subnet mask and the class of the IP address. The class of the IP address can be determined by the first octet of the address. In this case, the IP address is 192.168.1.0, which is a Class C IP address. Class C IP addresses have the default subnet mask of 255.255.255.0.
However, the subnet mask given in the question is 255.255.255.240. This is a custom subnet mask that has been applied to the Class C IP address to create a subnet. To determine the number of host addresses available on this subnet, we need to use the formula:
2^n - 2
Where n is the number of bits that are used for the host portion of the IP address. In this case, the subnet mask is 255.255.255.240, which is equivalent to a CIDR notation of /28. This means that the first 28 bits of the IP address are used for the network portion of the address, and the remaining 4 bits are used for the host portion of the address.
Using the formula 2^n - 2, where n = 4 (number of bits in the host portion), we get:
2^4 - 2 = 14
Therefore, the number of host addresses available on the network 192.168.1.0 subnet 255.255.255.240 is 14. The correct answer is option C, 14.
