What is the maximum number of subnets that can be created with a /22 subnet mask?
Step 1: Understand what a subnet mask is. A subnet mask divides an IP address into a network part and a host part.
Step 2: Know that a /22 subnet mask means that the first 22 bits of the IP address are used for the network part.
Step 3: Calculate the number of bits left for subnetting. Since an IP address has 32 bits, subtract 22 from 32. This gives you 10 bits left (32 - 22 = 10).
Step 4: Use the formula for calculating the number of subnets. The formula is 2 raised to the power of the number of bits left for subnetting. In this case, it's 2^10.
Step 5: Calculate 2^10. This equals 1024. However, if you are only looking for the maximum number of subnets, you need to consider the number of bits used for subnetting.
Step 6: Since we are using the remaining bits for subnetting, we can only create 4 subnets with a /22 mask (2^2 = 4) because we typically reserve some bits for the network and broadcast addresses.
