VLSM Revolutionizes Network Management with Efficient IP Addressing
A new IP addressing technique, Variable Length Subnet Mask (VLSM), is transforming network management. Unlike traditional subnetting, VLSM minimises IP address wastage by tailoring subnet sizes to host requirements.
VLSM stands out by not forcing all subnets to have the same size, thus avoiding unnecessary IP address usage. This technique offers numerous benefits, including efficient IP address use, flexible network design, reduced costs, improved network performance, and easy scalability.
To implement VLSM, network planners first create a detailed network plan. They then allocate the largest subnet first, followed by subnetting the remaining block. Routers are configured, and the setup is tested and verified before documenting the configuration. This process ensures optimal IP address allocation based on actual host needs.
VLSM, a key innovation in IP addressing, is attributed to the wider Internet Protocol (IP) standards development. It assigns different subnet masks based on host requirements, making IP address allocation more efficient. This technique is now widely adopted for its ability to minimise IP address wastage and enhance network performance.
