What is the maximum number of subnets that can be created from a Class B network

What is the maximum number of subnets that can be created from a Class B network with a subnet mask of 255.255.255.0?

What is the maximum number of subnets that can be created from a Class B network with a subnet mask of 255.255.255.0?

Step 1: Understand that a Class B network has a default subnet mask of 255.255.0.0.
Step 2: Recognize that the subnet mask 255.255.255.0 means we are using the last octet (the last 8 bits) for subnetting.
Step 3: Calculate how many bits are used for subnetting. The last octet has 8 bits.
Step 4: The number of subnets can be calculated using the formula 2^n, where n is the number of bits used for subnetting.
Step 5: Since we are using all 8 bits of the last octet for subnetting, we have n = 8.
Step 6: Calculate 2^8, which equals 256.
Step 7: Therefore, the maximum number of subnets that can be created is 256.
