(computing) Initialism of variable-length subnet masking.
CIDR is based on variable-length subnet masking (VLSM) to allow allocation and routing based on arbitrary-length prefixes. Source: Internet
Classless Inter-Domain Routing is based on variable-length subnet masking (VLSM), which allows a network to be divided into variously sized subnets, providing the opportunity to size a network more appropriately for local needs. Source: Internet
EIGRP adds support for VLSM (variable length subnet mask) and adds the Diffusing Update Algorithm (DUAL) in order to improve routing and provide a loopless environment. Source: Internet
The periodic routing updates do not carry subnet information, lacking support for variable length subnet masks (VLSM). Source: Internet
You can use an online conversion tool such as this CIDR / VLSM Supernet Calculator to convert from CIDR notation to IP address ranges. Source: Internet
When creating a subnetting plan using VLSM, you have to be much more careful in choosing what subnets to use. Source: Internet
