Task 1

Using TCP/IP as a reference model, show all the steps involved when Computer A(10.0.0.10/24) will send a message to Computer B(10.0.0.20/24) and Computer C (192.168.10.8/24).

Instructions:

• Given the above diagram representing a LAN and WAN, you are supposed to outline all of the stages that occur to accomplish the successful communications between two systems with diagrams and descriptions for each of the networks.

• You should make appropriate reference to each layer of the TCP/IP Reference Model.

• You can make reference to ping (ICMP protocol) usage and its description in each layer.

• You may also include the detailed description of functionality of the reference model chosen at each layer for every device that the packet travels through.

Task 2

You work for a large communications corporation named GlobeComm which has been assigned a Class A network address. Currently, the company has 1,000 subnets in offices around the world. You want add 100 new subnets over the next three years, and you want to allow for the largest possible number of host addresses per subnet.

Which subnet mask would you choose? Justify the reason for choosing the same.

Task 3

You are working as a network administrator for a large company ABC Comm with the base IP address provided 10.0.0.0/8 and has 16 subnets. You are seated at a workstation at the remote end of a network. You are attempting to troubleshoot a communication problem between that client workstation and the server at the other end of company. This workstation has a static IP address of 10.63.255.254, with a subnct mask of 255.240.0.0.

Because a particularly thorough security administrator, Frank, has removed most extraneous applications, including the Calculator, you must use paper and pencil to verify that the workstation is on the same subnet as your server at 10.112.0.1, with a subnct mask of 255.240.0.0. The user reports that the computer "hasn't worked right since it was installed last week." You cannot ping the server from the workstation. Are these two computers on the same subnet?

Instructions to the students:

• Based upon the above criteria you need to troubleshoot the reason behind the unreachability of the server from the workstation.

• As they are not able to ping you need to verify that they are in the same subnct or not.

• For achieving this you may need to compute the following:

o The Network address assigned to each office subnet.

o The address of the first Host in each network subnet.

o The address of the last Host in each network subnet.

o The broadcast address for each network subnet.

Clearly specify each step followed by you to calculate the corresponding addresses (i.e. the complete subnetting ilution).
