The automatic IP Calculator to do subnetting and supernetting.
The first App to calculate subnetting and supernetting in the most easy way.
IP Master Plan is better than a subnetting calculator, because it design your IPv4 network automatically based on the groups of host you will divide it. The app works with an algorithm to divide a given IPv4 in the optimal subnets to assign the directions to your groups. You can also bring these networks to the superneting module and calculate the IP network (supernet or supernetwork) that covers them all.
