Subnet Plus - Subnet Calculator is a free iPhone and iPad app that provides a convenient and efficient way to calculate and save networks. Designed for those learning subnetting, this app offers display options to show complete binary and hex information for calculated subnets. With its user-friendly interface, it serves as a valuable tool for individuals studying for CCNA, Network+, and other networking exams.

One of the standout features of Subnet Plus is the Binary Display, which helps beginners visualize the starting points of network and host addresses. By dividing an organization's IP network into subnets, it becomes easier to manage and connect to the internet using a single shared network address. This eliminates the need for multiple internet connections for physically separate subnetworks, maximizing the limited number of network numbers available.

Network engineers rely on Subnet Plus to calculate subnet masks, determine usable IP address ranges, identify broadcast IP addresses, and find network numbers. With its comprehensive functionality and user-friendly design, Subnet Plus is an essential utility for anyone working with IP networks.
