About this app

Simple VLSM Subnetting is a fast and easy-to-use IPv4 subnetting calculator designed for students, teachers, and networking professionals. Enter your base network and the hosts required for each subnet, and instantly get the complete addressing, ready for documentation or configuration.

WHAT YOU CAN DO
• VLSM Subnetting (Variable Length Subnet Mask): Each subnet receives the closest-fitting subnet mask for its hosts, making the most of the available address space.

• FLSM Subnetting (Fixed Length Subnet Mask): All subnets are the same size, sized for the most demanding subnet.

• Complete breakdown of each subnet: network address, broadcast address, subnet mask, CIDR prefix, required and usable hosts, and the range of assignable addresses.

• Decimal and binary representation, with network bits highlighted for a quick overview of how each block is formed.

• Save your calculations on the device and reopen, edit, or delete them whenever you want.

EXTRA TOOLS
• Number system converter: instantly convert between binary, octal, decimal, and hexadecimal.

• Clear glossary of networking terms (subnetting, CIDR, mask, broadcast, VLSM, FLSM, and more) for reviewing concepts.

IDEAL FOR
• Networking students and those pursuing certifications like CCNA or Network+.

• Teachers who need verifiable examples and results.

• Administrators and technicians who design or document IP addressing.
