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.
