Network Design for Silver Industries: Devices, IP Addresses, and Subnets

This presentation outlines the network design for Silver Industries, a mechanical company. It includes the required host list, router and switch configurations, VLSM, and end device configurations. The presentation also explains the use of Variable Length Subnet Mask (VLSM) and the different subnet masks used for different networks.

Network design

 The below diagram showcase the network devices and the connection which was
proposed for the silver industry.

Background
 Sliver Industries is a Mechanical company for which we are going to design the
network. For this whole design of network we are going to plan how many devices
does the company is in need of, the IP addresses of every device and the subnets for
the network. At last we need to decide the type of cable to be used for the network
connection by looking at the cost of designing the whole network structure.

End devices
 Every end devices is comprised with an IP address and default gateway. The default
gateway is the IP address of the respective router.

Router configuration
 Routers are also configured with different networks addresses.

VLSM
 Variable Length Subnet Mask, abbreviated as VLSM, is a means to specify a different
subnet mask for the same network number on different subnets. With VLSM, a
network administrator can use a long mask on networks with few hosts and a short
mask on subnets with many hosts.
