You have been appointed as a Network System Administrator by the SoftTech company in Sydney to allocate public IP Version 4 (IPv4) address into 3 different locations, “2 remote offices (Melbourne and Adelaide) and also one main office in Sydney”. The major task is to allocate the unreserved public IPv4 addresses to different offices.

Requirements:

Your network design needs 4 subnets:

1. Subnet A (Sydney): It requires 63 IP addresses (60 for PCs and 2 for servers (Windows, Fax), and 1 for router interface).

2. Subnet B (Melbourne): It requires 53 IP addresses (50 for PCs and 2 for servers (DNS, Database), and 1 for router interface).

3. Subnet C (Adelaide): It requires 43 IP addresses (40 for PCs and 2 for servers (Linux, Application).

4. Subnet D (Between two routers): It requires just 2 IP addresses.

You need to use routers and switches to make a connection among devices and also between networks. Each office has its applications, but some applications require inter-department data transfer. All workstations need internet access, company intranet access, and also access to a wireless network. You need to come with a design report and send it to your technical manager.

Report: The report must contain the following sections:

1. Introduction:

Critical analysis of networking requirements.

2. Local Area Network (LAN):

Design and description of Local Area Network for all subnet which must include:

a) Network topology; Discuss the reasons for choosing the particular network topology.

b) LAN design connections to the servers, connection to other subnets, and also the internet.

c) IP addresses: Find all network and host addresses including subnet masks according to the requirements by using the private address with your choice.

3. Hardware:

Provide a complete description of all interconnecting devices (switches, routers, hubs, and access points) and wiring used to build the network. Justify your choice.

4. Conclusion:

A comprehensive summary of the work done and recommendations.
