Open Source Windows IT Subnet Calculators

TeemIp is a free, open source, WEB based, IP Address Management (IPAM) tool that provides comprehensive IP Management capabilities. It allows you to manage your IPv4, IPv6 and DNS spaces: track user requests, discover and allocate IPs, manage your IP plan, your subnet space, your zones and DNS records in accordance with best in class DDI practices. At the same time, TeemIp's CMDB allows you to manage your IT inventory and links your CIs to the IPs they use. Project source code is located on https://github.com/TeemIP

An automated, Web based IP address management (IPAM) software. It features powerful search and filter functions for both networks and host, as well as many tools (e.g. a subnet calculator) helping Administrators to plan and handle complex IP networks

Administration of large networks could be a very time-consuming work. So this program should represent a comfortable solution for calculating subnets in IPv4-networks. First fo all it is designed for Windows but also executable under Linux/Mono.

This tool is designed to simplify the following networking calculations: Simple conversions between binary, hexadecimal, and decimal numbering systems. Determination of netwrok numbers based on an IP address and subnet mask. (Long-term) The process of subnetting a network into multiple networks based on the number of clients needed in each subnet.

A web browser based calculator written in HTML and JavaScript that will calculate the Variable Length Subnet Masking for your network. Simply enter your CIDR block address/mask and the number of addresses you need in each network, and it does the rest.

Given a valid IP address and subnet mask, this program will return the necessary subnetwork data.

This is a GUI wrapper for IPeek module (Python IPv4 Address Calculator). This little application can help with day-to-day IP address calculations.

IPv6SubnetCalc is a comprehensive calculator for IPv6 addresses. It comes with Java Swing GUI and supports the following RFCs: RFC4291, RFC4193, RFC3849, RFC2464, RFC5375, RFC4941, RFC3513, RFC3879, RFC4941, RFC3056, RFC3587, RFC2374, RFC3306, RFC3956.

Crossplatform utility that calculates network address, broadcast address, etc... by given IP and mask.

Shapley is a compilation of free PyGTK networking tools distributed under the BSD license.

A command which, for a given IP address and subnet mask, gives information about Network ID, broadcast address, first IP address, last IP address and network size. Examples using command: (ncalc 192.168.0.150 255.255.255.0) or (ncalc 192.168.0.150/24

Based on the IP address and subnet mask input from the user, the following values are calculated: #1. Network address #2. Broadcast address #3. Number of valid hosts #4. Wildcard mask #5. Number of mask bits (CIDR notation) #6. Random IP addresses from the subnet.
