Questions & Step-by-Step Solutions

What is the maximum number of hosts that can be accommodated in a subnet with a subnet mask of 255.255.255.240?
  • Step 1: Understand what a subnet mask is. A subnet mask helps to divide an IP address into a network part and a host part.
  • Step 2: Convert the subnet mask 255.255.255.240 into binary. It looks like this: 11111111.11111111.11111111.11110000.
  • Step 3: Count the number of '0's in the binary representation of the subnet mask. In this case, there are 4 '0's.
  • Step 4: The number of '0's tells us how many bits are available for host addresses. Here, we have 4 bits for hosts.
  • Step 5: Calculate the total number of possible addresses using the formula 2^number_of_host_bits. So, 2^4 = 16 total addresses.
  • Step 6: Subtract 2 from the total addresses to account for the network address and the broadcast address. So, 16 - 2 = 14 usable hosts.
