Ipinfo is a simple tool for calculation of IP networks - broadcast address, wildacrd address or count of usable IP addresses in a network, all of it based just on the knowledge of an IP address and network mask (or prefix length). The program is written in C programming language primarily on the Linux platform, however it should be possible to run it on other platforms too. As a product part of the package there is a program ipmatch, which can simple tell if given IP address belongs to a given subnet (or if it is a network or a broadcast address). Version 1.0 can be distributed and modified freely under the terms of GPL license, however version 1.1 and higher are distributed under the terms of this license: Licence Beerware, revize 42: As long as you retain this notice you can do whatever you want with this stuff.
