Using the host's formula Step 1. Find host range To use the host's formula, let's first look at a simple example. Say you plan to use the IP Step 2. Convert to binary Before you decide to use this subnet mask, however, let's apply the host's formula to it. To Step 3. Calculate the total number. How to Calculate Subnets Subnets and Hosts Borrow 2 bits S S H H H H H H # of subnets = 2 2 = 4 Subnet mask = 2 bits = + 64 = Range of hosts = 2 6 = 64 TT Range Useable Range Network ID 0 – 63 64 – 65 - – - Broadcast – Address Borrow 3 bits S S S H H H H H # of subnets = 2 3 = 8. Step 1: Determine how many subnet bits (1's), you have to add to the classful boundary to cover the number of required subnets. The IP address given was a class B address, making the first 16 subnet bits static. Using the cheat sheet, find the exponent of 2 that is equal to or greater than the number of subnets we require ().

г. These outputs are the subnet mask and IP address converted to binary format. These are helpful when manually subnetting networks. CIDR notation. Author show the correct method on how to calculate subnet mask, and the subnet mask are without calculate subnet mask manually. 15 авг. г. Calculate and apply an addressing scheme including VLSM IP addressing To determine the Broadcast IP of this IP address and subnet mask.
