ITECH1102 Networking And Security

Overview

The main objectives of this assignment are:

• To help students gain a good understanding of the IP (Internet Protocol), which is the major underlying technology of the
• To help students to understand the importance of subnet and routing of IP
• To encourage students to conduct an independent investigation into IP related topics from books, the Internet and through practical investigation.

Engagement with this assignment should help students to understand the primary underlying concepts of the Internet world.

Scenario

You have been appointed as a Network System Administrator by the Australian government to allocate public IP Version 4 (IPv4) addresses and build a routing table for edge routers to connect the Australian states as shown in Figure 1.

The IPv4 is an exhaustive list of IPv4 addresses for current Internet users in the world. However, in this scenario, you have the liberty to use the entire available unreserved public IPv4 addresses for the Internet users in Australia.

Tasks

The major task is to allocate the unreserved public IPv4 addresses to different states in Australia based on the number of Internet users in those states. The number of Internet users for each state is given below:

The task needs to be completed based on the following constraints and assumptions:

• Only unreserved public IPv4 addresses should be used for
• Each state should have a unique set of addresses - no address or set of addresses can be reassigned to any other
• You should use only the classless IPv4 addressing in the
• The number of allocated addresses for each state should not exceed by 20% of the specified Internet users for that particular state. For instance, the assigned addresses for Tasmania should not exceed 360 Thousand
• It is allowed to use one or more subnets to achieve the number of required address for a given

The minor task is to create a routing table for edge routers only for the state NT, WA and SA. The task needs to be completed based on the following constraints and assumptions:

• The routing table should be minimal with no redundant routes in the
• Any packets from the source (NT or WA or SA) should take the minimal route to reach the destination (NT or WA or SA).
• Identify the Network Interface Card address to connect NT, WA and

Assessment Details

All works submitted must be authored by the individual student submitting the work. Students found to  have     plagiarised will be        dealt     with      according         to         university

plagiarism         policy

Please note it is highly unlikely that two students would have the same set of addresses allocated for a given state.

Submission

Students are required to use the template supplied along with the assignment. The completed template with your name and student number (3 pages only) should be submitted through Turnitin in Moodle by Week 11
