Endpoint Calculator

The Network Endpoint Calculator allows users to determine the total available subnets, hosts per subnet, subnet mask in CIDR notation, and whether the network size is sufficient based on selected network class, subnet bits, and desired number of hosts.

Step-by-Step Guide to Using the Network Endpoint Calculator

Welcome to the Network Endpoint Calculator. This tool helps you determine subnet configurations based on your network class and other parameters. Follow the steps below to use the calculator effectively.

Step 1: Select Network Class

Begin by selecting the desired Network Class from the dropdown menu. The options available are:

  • Class A: Ranges from 1.0.0.0 to 126.255.255.255
  • Class B: Ranges from 128.0.0.0 to 191.255.255.255
  • Class C: Ranges from 192.0.0.0 to 223.255.255.255

Make sure to select the class that best fits your network requirements, as it influences the calculation of available hosts and subnets.

Step 2: Enter Number of Subnet Bits

In the input field labeled Number of Subnet Bits, enter the desired number of bits for subnetting. This value must be between 1 and 30. It determines the number of subnets you can create within the selected network class.

Step 3: Specify Desired Number of Hosts

Enter the Desired Number of Hosts in a subnet. This is a required field and should be a number between 2 and 16777214. This parameter helps the calculator determine if the selected subnet configuration can accommodate the specified number of hosts.

Step 4: Analyze Results

Based on your inputs, the calculator provides the following results:

  • Total Available Subnets: This calculation shows the total number of subnets you can create, computed as 2 raised to the power of the entered subnet bits.
  • Hosts per Subnet: Displays how many hosts each subnet can support. The calculation depends on the network class and subnet bits. It subtracts 2 from the maximum possible hosts to account for network and broadcast addresses.
  • Subnet Mask (CIDR): Shows the subnet mask in CIDR notation, calculated by adding the subnet bits to the base CIDR value of the selected network class.
  • Network Size Sufficient: Indicates whether the number of hosts per subnet is sufficient to meet your desired hosts. It will display ‘Yes’ or ‘No’.

Review these results to determine if your network setup is viable under the given parameters. Adjust the inputs as necessary to achieve a suitable configuration.
