1. Determine the total number of IP addresses available in the IP address range: – Count all the numerals in the IP address range (i.e., 192.168.1.0/24 = 8 numerals). – Subtract 2 from this number of numerals to get the total number of IP addresses available in the range (i.e., 8 – 2 = 6)
2. Calculate the number of usable IP addresses in the IP address range: – Subtract the Network ID (i.e., 192.168.1.0) and the Broadcast Address (i.e., 192.168.1.255) from the total number of IP addresses available in the range (i.e., 6 – 2 = 4). – The result is the number of usable IP addresses in the IP address range (i.e., 4).
