Variable Length Subnet Mask (VLSM) in IP Network Design

Play an AI-generated podcast conversation about this lesson

What is the main benefit of using Variable Length Subnet Mask (VLSM) in IP network design?

To decrease the number of hosts per subnet

To allocate IP addresses less efficiently

To allocate IP addresses more efficiently (correct)

To increase the number of subnets

What is the issue with traditional subnetting schemes?

They create more subnets

They allow for efficient use of IP addresses

They lead to wasted IP addresses (correct)

They require more network administrators

In a VLSM design, how are subnet masks assigned?

Using a fixed subnet mask for all subnets

Using the same subnet mask for all hosts

Using a smaller subnet mask for smaller subnets and a larger subnet mask for larger subnets (correct)

Using a larger subnet mask for smaller subnets and a smaller subnet mask for larger subnets
