Subnetting vs VSLM

Unanswered Question
Apr 19th, 2007

Is VSLM simply subenetting a Subnet. Does not make since to me still sounds like subnetting. I thought VSLM was subnetting not how to subnet a subnet. Kind of redundent isn't it? Can someone tell me the fundemental differences?

I have this problem too.

Subnetting allows you to create multiple logical networks allowing for network segmentation for reasons such as security, QoS, etc.

VLSM is a form of subnetting that allows you to use different subnet masks for different subnets in the network which makes more efficient use of address space.

Take a look at the following link for more details.
