0) = number of hosts The following are two examples: A. Divide Class B IP address 168.195.0.0 into 27 subnets Solution 1) 27 convert to binary = 11011 2) the binary is 5 digits, so n = 5 3) set the subnet mask of the Class B address to the first 5 locations 1 of the host address of 255.255.0.0 to obtain 255.255.248.0. This is the subnet mask of the Class B IP address 168.195.0.0 that is divided into 27 subnets. B. Divide the IP address 168.195.0.0 in
