VLSM (Variable Length Subnet Masking)

Variable Length Subnet Masking (VLSM) is a method used in computer networking to divide a single network into smaller, more manageable parts, or subnets, while allowing for different sizes of these subnets. This flexibility helps optimize the use of IP addresses, ensuring that larger networks receive more address space, while smaller ones get just enough. By doing this, VLSM improves network efficiency and organization, enabling better use of limited IP addresses and reducing waste, leading to more effective network management and performance.
