Arrange these steps for planning differently sized subnets from a supplied address space.

### Why this is right A designer first needs to know what each network must support. Only then can suitable block sizes be chosen, assigned from the available range, and checked for fit and efficient use. ### The order 1. Identify the network sizes or host requirements: subnet size depends on what each network must support. 2. Choose subnet blocks large enough for the intended networks: this applies VLSM to the stated needs. 3. Assign the chosen blocks within the available address space: the blocks must fit within the supplied range. 4. Check that the design uses the available address space appropriately: this catches waste or allocation conflicts. ### Terms - **VLSM**: Variable Length Subnet Masking. A way to define differently sized subnets. ### Remember Know the required network sizes before assigning subnet blocks.
