How Do You Calculate The Number Of Subnets?
Calculating subnets is a method used to determine how many host machine IP addresses are available. Subnet masks allow administrators to segment a network, allowing separate sections. Sub-networks lower the amount of packets on a large network, improving its performance. These sections are connected using a router. The subnet mask and its host IP addresses are registered with the network router, so each IP packet is routed to the proper subnet. Retrieve the network ID. Networks have standard IP address prefixes. For instance, a standard class B network has the prefix “172.16.” Class A networks have the prefix “10,” and class C have the prefix “192.168.0.” Determine the number of host addresses. Using the 172.16.0.0 network class, each zero represents 8 bits. Since there are two zeros (16 bits), the calculated number of available host addresses is 2 to the 16th power, or 2^16, which equals 65,536. Determine how many host addresses you need and round it to the nearest power of two. For i
