Steps in designing a computer network

1) Determine the physical network layout
2) List down the network address and default subnet mask
3) Determine the minimum subnets and hosts per subnet to be supported
4) If you are implementing subnetting, you need a new subnet mask.
5) Use 2^N and 2^H-2 to determine the subnet bits and hosts bits to use
4) Derive the new subnet mask.
5) List down the network addresses, range of usable host ip addresses and broadcast addresses
6) Assign the network addresses to each LAN segment
7) Assign and configure the host ip addresses to the host devices in each LAN segment
