Subnet a subnet?

By summersmummy ·
Hi,

I was wondering if anyone could help with a query? Can you subnet a subnet? I've trying to configure a network and have to work out subnets needed. Part of the information I have says a network must be further sub-networked to allow more users/networks. I'm slightly confused by this.

Thanks.

It's called Variable Length Subnet Masking (VLSM)

Variable Length Subnet Masking - VLSM - is a technique that allows network administrators to divide an IP address space into subnets of different sizes, unlike simple same-size Subnetting.
Variable Length Subnet Mask (VLSM) in a way, means subnetting a subnet. To simplify further, VLSM is the breaking down of IP addresses into subnets (multiple levels) and allocating it according to the individual need on a network. It can also be called a classless IP addressing.
