Questions & Step-by-Step Solutions
What is the maximum number of subnets that can be created from a Class B network with a /22 subnet mask?
Step 1: Understand what a Class B network is. A Class B network has a default subnet mask of /16.
Step 2: Recognize that a /22 subnet mask means we are using 22 bits for the network part of the address.
Step 3: Calculate how many bits are used for the subnetting. Subtract the default Class B bits (16) from the new subnet mask (22). This gives us 22 - 16 = 6 bits.
Step 4: Use the formula for calculating the number of subnets. The formula is 2 raised to the power of the number of bits used for subnetting. In this case, it is 2^6.
Step 5: Calculate 2^6, which equals 64. This means we can create 64 subnets from a Class B network with a /22 subnet mask.
