This calculator can also be used to do reverse subnetting where the number of hosts is known but the netmask is not. Open command prompt and browse to the installed folder and run python subnetcalc.py. if you're using windows, make sure you have Python2.7 set up (See Python installation on windows).

This is useful when studying and learning how to subnet and example practice networks are needed. If you're using Linux/MAC OS, open terminal and browse to the downloaded folder and run python subnetcalc.py. The subnet chart helps the network engineers to quickly and easily design a network. It also features a regular subnet calculator to discover the available hosts, address range, network address and broadcast address of a given IPv4 network. The tool also has the ability to create a random IP address which can then be calculated. This app divides networks into smaller more efficient subnets to meet host requirements. It is also intended to be a teaching tool and presents the subnetting results as easy-to-understand binary values. By giving a second netmask, you can design subnets and supernets.

This free online subnet calculator allows for the input of a netmask, a Cisco wildcard mask or /CIDR notation. ipcalc takes an IP address and netmask and calculates the resulting broadcast, network, Cisco wildcard mask, and host range. If you wish to save this subnetting for later, bookmark this hyperlink. Show columns: Subnet address Netmask Range of addresses Useable IPs Hosts Divide Join. The Number of hosts is calculated according to the following equation: Hosts (2n) - 2, where n is the number of bits set to 1 in the Netmask. Enter the network you wish to subnet: Network Address. The last usable address is calcualted by decrementing the Broadcast Address by 1. This allows for using keyword searches in Firefox.ĭ users can enjoy the !subnet bang command which makes use of this tool. Usable Addresses: The first usable host is calculated by incrementing the Network Address by 1.

It is possible to add the IP address to the URL to go directly to that IP and calculate it.
