## Description

Subnets and CIDR made simple.  Effortlessly calculate IPv4 subnets, Fixed Length Subnet Masks (FLSM), and Variable Length Subnet Masks (VLSM) all in a single app.

Subnetwork is a full-feature IPv4 subnet calculator that allows you to effortlessly calculate single subnets, Fixed Length Subnet Masks (FLSM) and Variable Length Subnet Masks (VLSM) using whatever IPv4 address and Classless Inter-Domain Routing (CIDR) notation you choose.  

Subnetting may be complicated and tedious, but that doesn't mean your user experience needs to be.  Designed exclusively for iOS, Subnetwork is a native and intuitive networking tool for students and IT professionals alike. 

Subnet Calculator - Calculate the subnet mask, wildcard, network ID, host range, broadcast addresses and more with an IPv4 address and dynamically adjustable CIDR prefix.

Fixed Length Subnet Mask (FLSM) Calculator - Instantly generate between 2 and 1028 FLSM subnets to meet your network and host requirements. 

Variable Length Subnet Mask (VLSM) Calculator - Instantly generate VLSM subnets to meet your custom host requirements and maximize your available address space. 

Simple and Powerful  - View minimal subnet details in decimal notation, or rotate your device for full binary calculations across all modes. View basic information at a glance in FLSM or VLSM, or dive into the details with just one touch. The choice is yours.

Save Support - Name, store, and retrieve your subnets for later use across all three calculator modes.
