Open Source Windows Networking Software

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.

You have to insert the proper numbers of the monitor you want to know how much bandwidth it will use. This program was designed to help find out what kind of connection you need to be able to run your monitor. Like 34BK95U-W (5120 x 2160 60hz) needs at least DisplayPort 1.3 to fully run it, becouse the program shows that it needs 18.4 Gbit/s, and DisplayPort 1.2 or older has 17.28 Gbit/s limit.

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

Network Speed Calculator is a tool to calculate the speed of downloads over various speed networks (including the internet). This program supports network speed, data size, number of simultaneous users and networks running under their intended speeds.

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

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.
