Computation and Allocation of IP Addresses in a Computer Network

Determining Individual Block IP Addresses and Allocating IP Addresses to Devices

Computation and allocation of IP addresses to devices in a computer network (based on a given block address), followed by design and simulation of the network using Cisco Packet Tracer software.

Each student must use their student’s number and the algorithm given below to determine their block IP address. Then each student must allocate an IP address to devices in the given scenario and configure the network using Cisco Packet Tracer software. This must be followed by simulation of the designed network and usage of debugging techniques (i.e. PDU or Ping command) to ensure satisfactory operation of all devices on the network

Use your student’s number to create your individual block IP address as follows: First section of IP

1. If first digit is 1 then take the first three digits as the first section of IP address.

2. If first digit is 0, then take the first three digit and replace the leading 0 by 1, for the first section of IP address. Second section of IP

1. Take the next 2 digits (digit 4th and 5th of your student number) for the second section the IP address;

2. If both are 0s (zeros) replace them by 11 and if only the digit 4th is 0 then ignore it (i.e. do not include it in your IP address).

1. For the third section of the IP address, take the following 2 digits (digit 6th and 7th);

2. If both are 0s (zeros) replace them by 11 and if only the 6th digit is 0 then ignore it (i.e. do not include it in the IP address). Fourth section of IP

1. The last section of the IP address must be zero Mask

2. Finally, the mask is /25.

1. It is the responsibility of each student to conduct research to check and confirm that their Block of IP address is not private or reserved.

2. The module teaching team must confirm your block of IP address and mask before proceeding to the next stage of the coursework.

Compute and determine the Network Address, Address Mask, Subnetting and other addresses in Table 2 using the lecture material and information from the recommended textbook as a guide.

Using the classless IP address computation techniques and block IP address and mask xxx.xx.xx.0/25 (address / mask) you obtained from Task 2.1.0 perform the following tasks:

• Determine the number of addresses in the network

• Last Host Address, the Broadcast and the Bit mask etc.

• Complete Table 2 below for each subnet class A, B, C, D, E, and F.

Conduct the above calculation for your IP addresses and design an IP address scheme that satisfies the requirements in Table 1 above.

• Show the step by step procedure you used to complete Table 2 below.

• Hints: - for the classless computation use either the binary or AND/OR approach or any other method in the recommended textbook/lectures.

• Students are required to show and explain steps used for IP calculation.

• For the sub-netting computation use the technique in the recommended textbook or any acceptable method but explain the procedure used.

o The Telnet password;

o The Aux port password;

o Console password;

o Enable password;

• Explain the steps you used to set up the above security systems.

• Use screen shots from the implementation to illustrate your work.

1. Question 1 Task 1: after allocating IP addresses, fill them in Table 2above and insert the table in your report.

2. Question 2 Task 2:Your topology must be saved as a packet tracer file with extension. pkt (Network_u1339611.pkt) and be uploaded to the Turnitin in  Moodle.

3. Question 3 Task 3: Types of cables used for connection between devices and subnets must be indicated. Complete Table 3 and insert it in the report. Host names on the table should correspond to the host names on your packet tracer file. Please make sure that your file is saved after all devices have been configured.

4. Question 4: Complete Table 4 above on this document and insert it in the report. The evidence of connectivity (results) of this question must be saved in the report.

5. Please follow instructions below:

a. Maximize the command prompt screen

b. Verify two connectivities each time, press PrtScr and paste it in the report file. Please indicate the name of the host (HOST1, HOST2 or HOST3) for each screen dump. At the end you will have 10 screens, which must be big enough to show commands and results.

c. Repeat the same verification using PDU. At end of all 20 verifications, double click on PDU List Window to make it bigger. Capture the screen by pressing PrtScr and paste it onto the report file.
