IP Calc is a must-have iPhone app for network engineers that performs IPv4/IPv6 address calculations with a single tap—now augmented by an AI Design Assistant for natural-language requests. It accelerates design and operations with accurate, explainable results, and it’s a one-time purchase (no subscription).
