Description by Nicolai Tufar (from the App Store)

IP Calculator is a fast, no-nonsense IPv4 subnet calculator for network engineers, students and anyone configuring a network.

Set an address and prefix with native iOS wheels: four octets (0-255) and a CIDR prefix (/0 to /32). Results recalculate live while the wheels spin, so you can explore subnets as fast as you can scroll.
